8 primary colours flashing (sorry)

u/joeytwiddle

I just made this to explain my 8-bit childhood trauma to a friend
u/joeytwiddle

Long ago I noticed that the brightness of the colours increases in an alternating fashion: 0,4, 1,5, 2,6, 3,7. Paste ,c.style.filter='saturate(0%)',t=0 at the top to see this. It seemed to me to be intentional but odd. Now I realise it's simply because blue is the darkest primary, with red and green following. So we can get a smooth gradient by moving J*(f&1) from the first argument to the last.
