Theory of color 1

Theory of color 1 Oil painting is inseparable from oil color, but oil color is not all oil painting. Oil painting cannot leave sketch, but oil painting is not equal to drawing sketch with color. The history of oil painting in the past five hundred years shows its basic characteristics and rules in color -- the law of conditional color. Without it, the essence and characteristics of traditional oil painting color techniques are also left. The use of conditional color, later than the use of decorative color. However, the discovery and development of conditional color law does not mean the decline and death of decorative color law, but the enrichment and development of artistic color skills, and a new field has been opened up in the hundred gardens. Painting, that is, the vividness of sketching colors, can not be obtained without mastering the law of conditional colors. The first key problem of conditional color law is the tone problem. In life, in art, color never exists in isolation, it is combined with the "form". But it has its own independent law. In life, color exists everywhere, it covers everything. In a work of art, to the viewer, it is the main color tendency of the work of art; For the creator, it is the commander and conductor of the artwork. Rich local cold and warm colors, if there is no tonal commander and command, will lose the unity of the overall color; It is bound to "flower", "chaos", disharmony; There is no uniform atmosphere, mood; It is difficult to achieve the effect of color expression, color lyricism and color freehand brushwork. Tone in nature, tone is the child of color light. The hue of the object image reflects the color characteristics of the light source. Different shades of light produce different hues. Several of Monet's different "Louen Cathedral" are showing different hues, depending on the hue of the light. The tone of the light side of the church changes according to the change of the sun color, and the dark side changes with the change of the sky color and the environment color. In the morning, the sun is warm and yellow, and the sky is blue and purple, shining on the light gray church, and the church's bright color tone is close to warm yellow with the sun, and the dark side is close to blue and purple with the sky. The light and dark sides of the church changed as the afternoon sun turned white and warm and the sky turned blue. The church at dusk is in the shadow of the backlight, unable to see the sunlit side, the whole church is affected by the sky light and slightly cold, standing in the sky full of warm light.
