The difference between red and scarlet in oil painting

Cinnabar and scarlet are warm colors, but cinnabar is yellow, so cinnabar is warmer than scarlet.

Cold and warm colors are a kind of color feeling. There is no absolute difference between cool colors and warm colors. Color exists in contrast. For example, vermilion is warmer than roses, and lemon yellow is colder than khaki.

The distribution ratio of cool color and warm color in the picture determines the overall tone of the picture, which is usually called warm color and cold color. The use of cold and warm contrast colors can make the picture more layered. In painting, different tones can also express artistic conception and emotion.
