The skills of color matching are as follows:

1. Strong contrast. When organizing fresh colors, the lines or blocks of achromatic color gold, silver, black, white and gray are embedded between the high-purity colors with strong hue contrast, so as to adjust the intensity of colors, buffer the original color matching and produce a new harmonic color effect.

2. Weak contrast. In order to remedy the weak and fuzzy feeling caused by the similarity of hue, lightness and purity between colors, this method is often used. Such as light gray-green, light blue-gray, light coffee, etc., when TINT is close, black lines are used to outline the interval, which can obtain clear, bright and lively shapes in many ways, without losing the soft, elegant and implicit color aesthetic feeling.

3. hue method. In many combinations, all colors contain a certain hue, so that the color matching can achieve both contrast and harmony. Such as vermilion, scarlet, rose and other TINT, in which the red phase is unified.

4. lightness method. In order to obtain the approximation of the brightness of the whole tone, all the colors participating in the combination are made to contain white or black at the same time. Such as pink, pink green, sky blue and other colors, from white to a bright and beautiful "pastel" tone.

5. Purity method. In order to obtain the approximation of the purity of the whole tone, all the colors participating in the combination are made to contain gray at the same time. TINT, such as green gray, blue gray and purple gray, is unified from gray to elegant, subtle and attractive gray tones.
