Isn't this just RGB, with 246 of the 256 values removed from each channel?

The point is that quantizing the range makes it easier for humans to choose colors. But there's already the #ABC hex format, which while less intuitive to non-techies has the huge advantage of being well-established.

		But it doesn't make it easier for humans to choose colors. For a specific list of detent colors, it reduces the amount you have to memorize relative to full RGB. But to actually reason about colors, you want a non-arbitrary scale; HSV (for instance) gives you hue direction and then you can slide saturation and brightness around.

It's rgb with 3.3 bits per channel, basically 10 bit per pixel color (256 colors is 8bpp).

My other question here is, are "R", "G", and "B" channels the best way to reason about color? Isn't HSV more intuitive?

		Or HCL? Or LAB? Any of these are more intuitive than RGB.
