Oil painting palette is made of wood, plastic, glass, metal and paper, and its shapes are rectangular, oval, round, folded and arm-shaped with arc curves. And it is more common to make it out of wood. The palette made of wood or plywood should be carefully polished and leveled, and coated with linseed oil or varnish twice in advance, so that the palette will no longer absorb oil.
In the past, the color of the palette was mostly brown, because most of the early oil paintings used dark backgrounds to facilitate accurate color matching. For example, if you use a light background, you can use a white and gray palette. In the mask dyeing stage of transparent painting, it is best to use the white palette to adjust the transparent color, so as to accurately predict the effect after coloring.
After each work, the remaining colors should be scraped off in time, and the palette should be scrubbed with solvents such as turpentine. Finally, the color palette can be scrubbed with linseed oil to make its surface smooth and level, which plays a certain protective role.
The paint that can't be used up that day can be carefully scraped off, put in a smaller glass plate, soaked in water and used next time. Covered paintings should be covered in time to prevent the paint from drying out.
Some painters don't always tidy up the palette and let the paint dry until it is weathered. Although the use of dry and wrinkled waste pigments can show special texture, it should be noted that the color left on the palette for a long time is in danger of losing cohesion due to the drying of oil.
Early western painters often put dark and light pigments on the palette in advance according to the color of the picture, while modern painters choose and reconcile the pigments on the palette more according to their personal habits and color needs.
Extended data:
The basic arrangement of pigments on the palette is regular, so it is convenient to find pigments and it is not easy to get the colors dirty.
Pigments are usually arranged in several ways:
One is based on the hue and lightness of colors starting from white, from light color to dark color, from warm color to cool color; The other is to take white as the center and arrange the cool color and warm color to both sides according to the depth; In addition, you can also add the same light color mixed with white under each main color.
