Pure saturated color {saturation, color}| {purity, color} has no white, gray, or black. White, gray, and black have zero purity. Spectral colors can have different white, gray, or black percentages (unsaturation). Saturated pigments mixed with black make dark colors, like ochre. Saturated pigments mixed with white make light pastel colors, like pink.
frequency range
The purest most-saturated color has light with one wavelength. Saturated color pigments reflect light with narrow wavelength range. Unsaturated pigments reflect light with wide wavelength range.
colors and saturation
All spectral colors can mix with white. White is lightest and looks least saturated. Yellow is the lightest color. Monochromatic yellows have largest saturation range (as in Munsell color system), change least as saturation changes, and look least saturated (most white) at all saturation levels. Green is second-lightest color. Monochromatic greens have second-largest saturation range, change second-least as saturation changes, and look second-least saturated (second-most white) at all saturation levels. Red is third-lightest color. Monochromatic reds have average saturation range, change third-least as saturation changes, and look third-least saturated (third-most white) at all saturation levels. Blue is darkest color. Monochromatic blues have smallest saturation range, change most as saturation changes, and look fourth-least saturated (least white) at all saturation levels. Black is darkest and looks most saturated.
calculation
Whiteness, grayness, and blackness have all three primary colors (red, green, and blue) in equal amounts. Whiteness, grayness, or blackness level is brightness of lowest-level primary color times three. Subtracting the lowest level from all three primary colors and summing the two highest calculates hue brightness. Total brightness sums primary-color brightnesses. Saturation is hue brightness divided by brightness. Assume colors can have brightness 0 to 100. If red is 100, green is 100, and blue is 100, whiteness is maximum. If red is 50, green is 50, and blue is 50, grayness is half maximum. If red is 25, green is 25, and blue is 25, grayness is quarter maximum.
Assume maximum brightness is 100%. If red is 33%, green is 33%, and blue is 33%, brightness is 100% = (33% + 33% + 33%), whiteness is 100% = (33% + 33% + 33%), hue is white at 0%, and saturation is 0% = (0% / 100%). If red is 17%, green is 17%, and blue is 17%, brightness is 50% = (17% + 17% + 17%), whiteness is 50% = (17% + 17% + 17%), hue is white at 0%, and saturation is 0% = (0% / 50%). If red is 33%, green is 33%, and blue is 17%, brightness is 83% = (33% + 33% + 17%), whiteness is 50% = (17% + 17% + 17%), hue is yellow at 33% = (33% - 17%) + (33% - 17%), and saturation is 40% = (33% / 83%). If red is 67%, green is 17%, and blue is 17%, brightness is 100% = (67% + 17% + 17%), whiteness is 50% = (17% + 17% + 17%), hue is red at 50% = (67% - 17%), and saturation is 50% = (50% / 100%). If red is 100%, green is 0%, and blue is 0%, brightness is 100% = (100% + 0% + 0%), whiteness is 0% = (0% + 0% + 0%), hue is red at 100% = (100% - 0%), and saturation is 100% = (100% / 100%).
Assume colors can have brightness 0 to 100. If red is 100, green is 50, and blue is 50, red is 50 = 100 - 50, green is 0 = 50 - 50, blue is 0 = 50 - 50, brightness is 200, whiteness is 150 = 50 + 50 + 50, and hue is pink with red saturation of 25 = 50 / 200. If red is 100, green is 100, and blue is 50, red is 50 = 100 - 50, green is 50 = 100 - 50, blue is 0 = 50 - 50, brightness is 250, whiteness is 150 = 50 + 50 + 50, and hue is yellow with saturation of 40% = (50 + 50) / 100 = 100 / 250. If red is 75, green is 50, and blue is 25, red is 50 = 75 - 25, green is 25 = 50 - 25, blue is 0 = 25 - 25, brightness is 150, whiteness is 75 = 25 + 25 + 25, and hue is orange with saturation of 50% = (50 + 25) / 150 = 75 / 150.
