Its contrast depends largely on the color levels with equal brightness differences. Generally, 1-3 is classified as low brightness area, 8- 10 is high brightness area, and 4-7 is medium brightness area. (Figure) When selecting colors for combination, when the interval between the primary color and the contrast color is greater than 5 levels, it is called long (strong) contrast, 3-5 levels are called medium contrast, and 1-2 levels are called short (weak) contrast. According to this, it can be divided into nine basic types of lightness contrast. (figure)

In color design, purity contrast is the key to determine whether the color tone feels gorgeous, elegant, simple, vulgar and subtle.

The intensity of its contrast depends on the distance between colors on the color scale such as purity. The longer the distance, the stronger the contrast, and vice versa.

If the gray to pure bright color is divided into 10 arithmetic progression, 1-3 is usually divided into low purity areas, 8- 10 is divided into high purity areas, and 4-7 is divided into medium purity areas (as shown in the figure). When choosing hue, when the distance between the primary color and the contrast color is above 5 levels, it is called strong contrast; Grade 3-5 is called medium contrast; 1-2 is called weak contrast. According to this, nine basic types of purity comparison can be divided. (figure)

(4) It is appropriate and popular to emphasize such as 4: 6: 10 or 7: 5: 1.

(5) If the middle key is 4: 6: 8 or 7: 6: 3, it feels gentle, static and comfortable.
