Points To Pay Attention To When Adjusting The Color Of Oil Paint

1. Only the white color (especially zinc white) cannot be mixed with pure oil, and all other pigment powders can be prepared with raw linseed oil.
2. The white powder will change color soon after mixing with pure oil, it is best prepared with emulsion, cellulose and casein emulsion binder can be used. This kind of lotion dries quickly, and the prepared color must be sealed and packed, and take as much as you use.
3. For thicker and granular pigments, it can be ground finely while adjusting the oil.
4. For oil painting colors in lead tubes, oil-absorbing treatment can be carried out before painting (such as squeezing on newspaper to make the paper absorb the oil in the paint), and the Medium oil-based medium can be adjusted when using it.
5. For light and color pigments with strong chroma, it is necessary to properly mix and write additives. Generally, materials such as talcum powder and Gaocen soil can be used.
For opaque colors with strong covering power, a proper amount of talcum powder can also be added. Gaocen soil, a material that only increases the volume without changing the pigment, can weaken the intensity of light colors or make opaque colors transparent.
6. For the pigment powder that floats after encountering water or oil, a little ox gall or alcohol can be added in an appropriate amount to make the pigment powder have adhesion.
7. Penetrating pigments should not be ground too finely, otherwise they will be discolored.
8. When grinding lead-containing and other toxic pigments, prevent the powder from entering the nose.
9. For the pigments developed with linseed oil, the overlay can only be applied when the underlying pigments are completely dry. Therefore, it is absolutely not possible to use the extremely impasto painting method for painting. It is most suitable for one-time painting and monochromatic painting.
