I'm hoping this doesn't get too compressed.

I've been looking into lightsabers again recently and they all claim "infinite colors", which just isn't true. What you see here (if it shows up correctly) is HALF OF ALL POSSIBLE COLORS.

Far from infinite, the number of possible colors for a light emitting object is already half of all possibe colors, that range being from RGB(0,0,0) to RGB(255,255,255) and brightness 0-255, giving you, when aligned like in this image (256+256)x(256+256)=262.144 colors, but since everything that's not a full value can be discarded, because that would just be less light/not full brightness, we end up with only the full value range (256+256)x(256+256)-(128+128)=261.888 (I just realised that's three quarters) colors. I filled that part in wiht cyan here, because the two edges on green and blue that lead to cyan would normally touch.

This is the maximum your LEDs if driven by RGB values as we know them can produce! Not infinite, not even functionally infinite.

This image (if displayed correctly) should show half of those, or 65.408 colors, since I skipped every odd value.

Now the real sad part about this, is that our eyes aren't sensitive enough to see the subtle differences, even in the half as big color-space. You can try and count the number of distinct colors you can see, but for most people it's not more than about 12. (You can't tell the difference between (255,16,2) and (255,4,14) really well, it's just red.)

And suddenly the advertised "infinite colors" of your lightsaber have been reduced to 12, maybe 16 with two different whites and that's really all you need.
