Color matching information in photography

1. Warm color. That is, the collocation of red, orange, yellow and ochre. The use of this hue can make the home page present a warm, warm and enthusiastic atmosphere.

2. Cool colors. That is, the collocation of cyan, green and purple. The use of this hue can make the home page present a quiet, cool and elegant atmosphere.

3. Contrast tones. That is, colors with completely opposite colors are collocated in the same space. For example: red and green, yellow and purple, orange and blue, etc. This kind of color collocation can produce a strong visual effect, giving people a bright, lively and festive feeling. Of course, if the contrast color is not called well, it will be counterproductive and produce tacky and dazzling adverse effects. It is necessary to grasp the important principle of "harmony between big and small", that is, the overall tone should be unified and harmonious, and there can be some small strong contrasts in some parts.

Finally, consider the depth of the background color of the home page. A term borrowed from photography here is "high profile" and "low profile". Light background color is called high-profile; The deep background color is called low-key. If the background color is dark, the text color is light, and the light content (text or picture) is set off with a dark background; Conversely, if the background color is light, the text will be dark, and the dark content (text or picture) will be set off by the light background. This change in depth is called "lightness change" in chromatics. On some homepages, the background color is black, but the text is also dark. Because the brightness of colors is close, readers will feel very tired when reading, which will affect the reading effect. Of course, the brightness of the color can't change too much, otherwise the brightness contrast on the screen is too strong, which will make the reader's eyes unbearable.
