Plotting Named Colors

Post by anthony »

I have always had an interest in the distribution of colors in colorspace.

This is not a problem, but I hope to start a discussion...

I have always felt that 'Named' Colors do not really map the whole colorspace very well.
Now I have proof.

The above was generated using a Programmed Positioning Technique in the script hsl_named_colors.

The named colors were first sorted into 3 groups, Off-Whites, Mid-Tones, and Dark Colors, and then plotted into a HSL color-wheel. White and Black colors appear as there own separate spots at the very top and bottom of the chart.

As you can see you there a lot of color names associated with red to yellow and a smaller group in the cyan to green hues. With a similar cluster in off-white yellows and cyans. But there is little in the way of named off-green colors. Essentially there are some areas of the color space that have little to no named colors.

It is also a 'limited' demonstration of how colors are arrange in 3 dimensional HSL colorspace.

Any thoughts about similar displays for other (non-RGB) color spaces. Like how would you arrange XYZ colors, which has generally been a bit of a mystery to me.
