I've posted the color words before. These words describe the hues of color, or what we would think of as the colors of the rainbow. We can also talk about the saturation and brightness of colors.
Saturation is how vivid or pale a particular color is. The scale of this is described with the words raxi for high saturation, and hili for low saturation. Here are some examples where the word is the color being discussed.
Note: These translations of the words raxi and hili is only in regards to color. They can be used to discribe light as well, but they do not mean saturated. They mean the level of light, similar to bright/dim.
Brightness is how dark or light a particular color is. The scale is described with the words Peibu and Hexi. These are also the words for white and block respectively. So the close to white the color is the more bright it is.
