Color composition homework lightness nine and hue contrast Who has a simpler picture to get me a thank you?

According to Munsell's color stereo theory, the arithmetic of brightness from black to white is divided into nine levels, so 1-3 is a low brightness level; 4-6 is the middle lightness scale; 7-9 is a high-definition color code. ?

"Brightness" refers to the brightness of a color. White has the highest brightness and black has the lowest brightness. Different shades have different lightness. Yellow has high brightness, while red and blue have low brightness. Any hue, such as white, will improve the brightness, and the more white components, the higher the brightness; If any tone is adjusted to black, the brightness is relatively low, and the darker the tone, the higher the brightness. ?

Extended data:

Tone contrast:

After more than two kinds of color matching, the color contrast effect caused by hue difference is called hue contrast. It is a basic aspect of color contrast, and its contrast intensity depends on the distance (angle) between hues on the color ring. The smaller the distance (angle), the weaker the contrast and the stronger the contrast.

Tone type:

Tone tendency can be roughly summarized as bright tone, gray tone, light tone, dark tone, middle tone and so on.

picture contrast

When contrasting tones, if the ratio of the surrounding colors to the pattern area is large, the closer the lightness is, the more obvious the effect is and the sense of contrast is enhanced. In addition, the matching of high-purity hue series will make the contrast effect more obvious.
