(Or maybe they were originally dyed and the color faded over the last 200 years.)
Whereas before you might've been limited to a choice of lighter or darker wood for your furniture, now you can have it in any synthetic color you want, including pure black and pure white.
Yeah I'm pretty skeptical of that visualisation anyway. It sure looks like there's more grey scale, but that's because they've grouped it all at the top. If you actually look at the pixels in the below "white" a lot of them are very dark and unsaturated too.
I don't think it's really a meaningful visualization. They're trying to show something 2D in 1 dimension.
