Color matching method suitable for patterns and the like

When you adjust a new color, you can adjust it in the color you use, that is, on the palette, because it is influenced by the environmental color. (But if it's bright, it's better to adjust the color again. For example, the jar is green and the cloth is dark red. For example, when it is gray, white can be added to the background between the two colors, and it is better to mix the three colors together.
