Multiple choice: what do we call the brightness of a color, in relationship to black? a) value b) hue c) purity d) saturation

Hi there!

From what I know, the brightness of a color, in relationship to black, is a) value. Purity means that it has no black, white, or grey in it. Saturation is on a scale of 1-100, determining how transparent the color is. And hue is in relationship to the three prime colors.

Hope this helps!! :)
