Color is the first thing we observed cognitive, is the most able to touch our senses visual elements. Colors can stimulate our association, stimulate our emotions. In the design, the reasonable use of color has been a very important issue, I summarize here some color part of the common sense to others.
First, the color ring
Primary colors of red, yellow, and blue components. In traditional color theory (mainly used in paint and pigment), the three primary colors are three colors can not be mixed with each other, all other colors are derived from these three colors.
With these three primary colors, we can go to create secondary colors (Secondary colors): green, orange, purple.
Mixing primary colors and secondary colors, we can get the so-called tertiary colors (tertiary colors): orange, orange, purple, violet blue, blue-green, yellow-green.
We will synthesize all of these colors is called color ring.
Color ring may be divided into warm and cool. Warm is vivid and full of energy, which tends to extend in space. And it gives people a warm feeling of calm and soothing, it tends to subside in space.
Second, the color matching
With common methods are: color with color, complementary color matching, tri-o-color matching, color matching similar, the difference in color matching, an equilateral triangle (Triad) color, the color complementary color, split complementary color, rectangular (four yuan) color , a regular tetragon (square) color, as shown below.
1. same color matching : the unity of color, primary colors and secondary colors of the same color is composed of one color hue are on the same hue, the entire screen may be embodied unity. This color can be easily formed while monotonous flavor, so there are some appropriate variations in purity and brightness, enhance the contrast in the area of the screen is more balanced.
2. matching complementary colors: color wheel opposite to each other are considered complementary colors are complementary colors (e.g.: purple and yellow) . High contrast of complementary colors to create a vibrant appearance, especially when using a fully saturated. This color scheme must be managed, it will not be stimulated. Complementary color difficult to use at high doses, but when you want to highlight something very good. Complementary color really bad for text.
3.三邻色配色：在色相环上相邻的色彩，有一定的色相差但不是很大，可以营造和谐的氛围，并且有丰富的质感和层次。所以配色效果比同色系配色稍微丰富，柔和过渡的色相使得页面看起来更加和谐。
4.类似色配色：类似色色相上含有共通成分，配色也可以体现出和谐、协调的印象，这种配色是最能体现出色相差的配色类型。类似色的色彩具有适度的变化和动感，同样可以用过色相差体现画面色彩的张弛效果。
5.中差色配色：中差色色相上基本没有共通性，色彩包括了类似色色相到对比色色相，搭配出一种暧昧的印象，表现出舒适感和适度的刺激效果。
6.正三角形(三元)配色：对比色配色也叫相反色配色，色彩对比效果十分强烈。即使您使用浅色或不饱和版本的色调，三重色调也会非常生动。为了成功地使用三重和谐，应该仔细平衡颜色 - 让一种颜色占主导地位并使用另外两种颜色作为重点。
7.互补色配色：互补色在色相环的相对位置，色相差较大，配色体现出十分强烈的视觉冲击效果。同时也容易形成廉价、劣质的印象。
8.分裂互补配色 :分裂互补色方案是互补色方案的变体。除基色外，它还使用与其补色相邻的两种颜色。该配色方案与补色配色具有相同的强烈视觉对比度，但张力较小。分体免费配色方案通常是初学者的不错选择，因为它很难搞砸。
9. 矩形（四元）配色：矩形或四元颜色方案使用四种颜色排列成两个互补对。这种丰富的配色方案为变化提供了充足的可能性。如果你让一种颜色占优势，四色配色方案效果最好。您还应该注意设计中暖色和冷色之间的平衡。
10. 正四边形(方形)配色：矩形或四元颜色方案使用四种颜色排列成两个互补对。这种丰富的配色方案为变化提供了充足的可能性。如果你让一种颜色占优势，四色配色方案效果最好。您还应该注意设计中暖色和冷色之间的平衡。
三、使用技巧
色彩的搭配方法有很多，这里介绍我个人比较认同的方式：70%，25%，5%的配色比例原则，画面中70%为底色，面积最大的一块，往往画面的色调是有底色决定的。25%面积的为主色，画面的核心区域多使用主色区。5%为强调色，强调色在画面中起到画龙点睛的作用，强调色多使用与主色对比度较大的颜色，也可以尝试利用色彩的互补关系来突出。
当然，在实际工作中，很多时候画面不会只有三种颜色。遇到这种情况时，我们可在现有的配色方案中进行切割，从而不影响配色比例。
