Frequently asked question 11

Solid yogurt added with an emulsifier will keep its soft creamy state for a long time, while yogurt containing no emulsifier will have clear liquid floating on top. However, the one [yogurt?]  without an emulsifier is better for health.

Likewise, paints containing no chemical additives may not look good, but they produce a better outcome than those with chemical additives.

As mentioned above, we, Mijello, add no thickeners, dispersing agents, and emulsifiers in the manufacturing process.

Usually, thickeners, dispersing agents, and emulsifiers are added to paints.

Paint containing such chemicals has a high viscosity when squeezed onto a palette, but neither will a medium (sealant) be isolated nor will there be cracks.

However, those chemicals will lower the purity of a drawing and deteriorate the preservability of the picture.

Since Mijello MISSON Gold is used by professional watercolor artists, it is not manufactured using chemicals, but rather is made by hand, focusing on the preservability, that is light fastness, of the artwork.


In using a palette, staining is an inevitable problem.

For steel palettes, the part coated with oil gets stained, and cannot be used any more once the part has been peeled off.

However, Mijello palettes are made of white material (resin) whose mixing part is not coated.

Therefore, mixing watercolors is much easier on it compared to a surface coated with oil because the separation phenomenon of surface tension decreases.

Please note the following instructions to remove stains on palettes and to keep them clean.

1. Wipe the palette with the enclosed Magic Cleaner frequently. The cleaner, made of melanin resin, will remove stains from the mixing part of the palette.

2. Mijello Watercolor Absorption and Cleaner will make it easy to clean a palette, and it is also good for absorbing water from brushes.

If a palette is wiped with either Magic Cleaner or Absorption and Cleaner, the palette will become whiter and last longer.


Each pigment has its own distinct property, and pigments with a low water content harden relatively fast. However, in many cases, the main reason why paints become dry is due to a problem with the tubes.

It is possible that the cap becomes stiff because the cap of the tube is not tightened enough to prevent direct contact with air. However, the inner substance doesn’t become hardened.

If the paint doesn’t come out of a tube because it is too stiff, it is obvious the paint is defective. However, if the head of the tube is dry, there is a possibility it had direct contact with air.

A hardened paint doesn’t mean the paint is old. A paint usually lasts at least four to five years and is still usable. Rather, over time, in the absence of air, the color inside a tube becomes mature and the color is enhanced over time.

After squeezing paint, make sure to close the cap tightly in order to keep the paint from getting hard.


Before 2009, cadmium was such a popular material that approximately 10% of the world’s total output was used in the manufacture of pigments. However, cadmium is a heavy metal.

The metal is easy to process in that it is resistant to heat as well as acid and base and has a good malleability (an ability to deform under pressure). It has been widely used in pigments for bright colors, such as yellow (cadmium sulfide) and red (cadmiumslelnid).

However, cadmium is a typical harmful metal and is classified as a Class 1 carcinogen.

Once entering the body, cadmium is accumulated in the liver and kidneys and is never released, causing a pollution-related disease, known as itai-itai disease.

If cadmium dye gets on a human hand, the substance will penetrate the skin. Even after completing a painting, if you don’t put it in a frame right away, harmful particles will travel through the air and enter the body through a respiratory organ, and be stored inside the body.  

In addition, the water containing cadmium dye enters the sewer system and harms the environment, threatening the health of others. Therefore, no MISSION products contain cadmium pigments.  

The colors of MISSION Gold, that can be used instead of those made from cadmium pigments, are Permanent Red Deep (PR254), Permanent Yellow Light (PY154), and Red Orange (PO73).

Compared to cadmium dye, the pigments for these three colors have much better chroma and definition. They are also not harmful to humans and have excellent light fastness. However, the price is higher than that of the cadmium pigment, which is a disadvantage for the producer.


Preservatives are added to prevent organic matter from multiplying and decaying.

In the process of making paints, adding preservatives is essential to preserve the products.

A small amount of preservative is added to MISSION watercolors during the process.

However, MISSION uses only cosmetic preservatives and minimizes elements that might be harmful to humans.

Since colors, as industrial products, don’t come in contact with human bodies, industrial preservatives are usually added. These preservatives include a large amount of formaldehyde, a known carcinogen. 

Because MISSION’s development team is well aware that colors sometimes get on people’s hands while in use, only a small amount of safe cosmetic preservatives is used to protect the users and the environment.


MISSION Gold Class was developed for professional watercolor artists.

These paints are excellent for cotton watercolor paper, which is used by many artists. When they are used, the particles of pigments are designed to be absorbed and firmly fixed into the paper.

In addition, drying hours are regulated so users can have a satisfactory outcome when they adopt spreading and spilling techniques.

Another important factor in developing MISSION Gold Class is light fastness so the colors won’t fade easily due to exposure to sunlight.

The watercolors of MISSION Gold Class are being used by a number of professional watercolor painters from Korea and all across the world, who work with valuable works of art. For those watercolor artists who want to preserve their works for a long time, light fastness is an extremely crucial factor.

Some pigments tend to have lower chroma when their light fastness is high.

The representative colors of MISSION Gold Class include pigments with high light fastness, such as yellow light, orange, and Van Dyke brown, because MISSION Gold Class puts light fastness over chroma.

MISSION White Class was developed with a focus on practical art, design, and illustration and it can be used as both watercolors and poster colors at the same time.

MISSION White Class has a better color formation than light fastness. As it is composed of pigments with high chroma, it is perfect for bright and beautiful colors. In addition, it was developed for drawing paper (Kent paper) which has a thinner absorption layer than cotton watercolor paper, so it dries quickly.

Since all 34 colors of MISSION White Class contain no white pigment, it is possible to portray a transparent watercolor by only regulating water. If the colors are mixed with design color white paint, which can be separately purchased, they can be a substitute for a poster color.

When mixed with 100ml of MISSION Design Color matte white, it serves as a matte poster color possessing a good concealing power and rendering a feeling of glossy gouache while also possessing a good concealing power when mixed with 100ml of MISSION Design Color glossy white, making it possible to express a wider range of artwork.

Both MISSION Gold Class and White Class contain neither cadmium pigments nor chemical additives. Also a small quantity of cosmetic preservatives, rather than industrial preservatives, is added to ensure safe use.


Since each pigment is made up of different ingredients, their chemical properties and particle sizes differ. Furthermore, a medium (sealant) is water soluble while a pigment is insoluble, so a pigment and a medium are separated unless an emulsifier is added. 

The reason why Mijello doesn’t use an emulsifier is that it is a chemical additive and degrades both the purity and preservability of colors.

The pigments with light particles and high water content are not easily isolated. However, the pigments with large, heavy particles and the pigments for white, ultra marine, Indian red, cobalt turquoise, cobalt blue No.2, and gray can be easily isolated. 

Though the timing for each color varies according to the pigments used, a medium and a pigment can be separated more easily some time after they are manufactured. However, since they undergo a curing period in a tube, such colors will have a better color formation than the ones just manufactured.

In this regard, if you see isolation after squeezing paint out of a tube, you can mix the medium and the color with an art knife. It won’t have any negative effect on the color; rather, you will see a better color formation.


Compared to colors manufactured by other companies, the colors of MISSION have a high color formation.

It is easy to lower color formation but extremely hard to enhance it in the manufacturing process. This is where a high level of technology is required. This is especially true when strengthening the color formation of some mineral pigments due to their unique properties. However, despite all those difficulties, MISSION has set its color formation level high for the following reasons.

First, we are committed to providing our customers with the best-quality colors. Second, we decided to set our standards high, hoping that our products can be applied to pieces with a high chroma level.

Many of those who use MISSION for the first time are surprised by the strong color formation levels. However, the reason for the high color formation standard is that since the staff of our development team were either art majors or had hands-on experience in drawing, they were able to think from the same perspective as users.

We are well aware users would feel very frustrated and helpless if they could not have the strong colors they want for their artwork.

Only water needs to be added to make weak colors, while the opposite is impossible. Therefore, the high color formation levels of MISSION colors make it possible to create a variety of colors by adding more water and generating colors with low brightness when trying to give an impression with light colors. In addition, for those who can express various colors by mixing colors, MISSION’s strong color formation provides a broader spectrum of colors.


The image of the ones with less foam or no foam would look better than those of the ones with foam.

However, it is possible that a lot of foam is generated in the mixing process as well as in the filling process due to the pressure of a machine. The foam is filled into tubes and pans. Therefore, foam is spotted when a tube is squeezed or a case is opened.

However, it is extremely easy to get rid of foam by using an antifoaming agent.

With the right amount of antifoaming agent, foam will quickly disappear, and foam will not appear when squeezed out of a tube.

However, no antifoaming agent is used by Mijello in any of its MISSION colors.

The reason is that the agent is a chemical additive that will adversely affect both the purity and preservability of our products.

Instead, we use a defoamer to remove foam. However, as colors containing no antifoaming agent are filled, it is difficult to get rid of all the foam.


Solid watercolors come in two types: compressed and filled.

After the viscosity of watercolors is maximized, the colors are placed into a machine and compressed, and then they come out as thin sticks. The sticks are then cut according to the size of each pan.

Most manufacturers prefer this method of making watercolors because drying periods are usually short, and the processes are relatively simple.

For compressed watercolors, there is no dip in the middle. However, the color formation is not good, and they sometimes fall off pans while in use because they are just laid on a pan.

All of the solid watercolors of MISSION are filled into pans.

They are first placed in pans and dried in a drying room for 20 days in order to remove moisture. The drying room is preset to the required temperature and humidity. After going through the same filling and drying processes two or three times for two months, MISSION solid watercolors are created.

Although the process is difficult and time-consuming, the color formation is excellent and the colors don’t fall off the pans. Although the same amount is filled on a pan, the shapes of MISSON solid watercolors can vary after the moisture is removed since the particle size and pigment weights differ.
