Add "pastel set luminance"
sharkdp opened this issue · comments
This is not as straightforward to implement like the rest of the properties. The way this should be implemented is probably by (only) adjusting the L
ightness channel in Lab
space until the luminance has the right value.
If there is no direct way to compute the correct L
value, we could also perform a (binary) search in L
space until we have the right luminance value.
