Third, the color contrast
Two or more colors can be compared with each other in terms of space or time, and they can make a significant difference, and produce a comparative effect, which is called color contrast. The imagination is divided into two major categories: simultaneous contrast and continuous contrast.
1. Color contrast ratio The contrast formed by the difference between hue. When the main hue is determined, it is necessary to consider what other colors are related to the main hue and what contents and effects are to be expressed so as to enhance its expressiveness.
Put the same orange, red or yellow, we will find that the orange on the red will have a yellowish feeling, because orange is red and yellow, when he and red, the same ingredients The parts that were reconciled and different were enhanced, so they looked yellower than when they were alone, and they were also compared with other colors. We call this name comparison. In addition to the color shift, the contrasting two colors sometimes have a phenomenon of mutual color permeation, and influence the visual effect of dividing the boundary. When the two colors of comparison have the same saturation and brightness, the contrast effect is more obvious. The closer the two colors are to the complementary color, the stronger the contrast effect.
2. Comparison of lightness The contrast formed by the difference between lightness. (The lemon has a high yellowness, the blue-violet lightness is low, the orange and green are light, and the red and blue are low light).
Brightness contrast will be the same color, placed in black and white, the feeling of color, will find the color on the black feel brighter, on the white color feel darker, the contrast between light and shade is very strong and obvious, on the color results The impact of the difference in brightness, which is very different, can make people feel uneasy.
3. Comparison of Purity When one color is compared with another, more vivid color, it will feel less distinct, but when it is compared with the color that is not bright, it is clear, and the contrast of this color is called purity contrast.
4. Complementary Color Contrast The colors with complementary colors of red and green, yellow and purple, blue and orange are juxtaposed with each other, making the color more vivid and the purity increased. This is called complementary color contrast. (Visual residual phenomena are obvious).
5, contrast between the cold and warm due to the color of the cold and warm differences formed by the color contrast, known as cold and warm contrast. (Red, orange, and yellow make people feel warm; blue, blue-green, and blue-violet make people feel cold; green and purple intersperse with them). In addition, the contrast between color and temperature is also affected by lightness and purity, and white light reflects high and feels Cold, black absorbs high and feels warm.
