A few years back I dug into the world of colormaps and was thrilled when the viridis, magma, plasma, inferno and cividis colormaps were created. But the fact that the darkest colors in viridis and plasma (and to a lesser extent cividis) are not black has struck me as a bit odd and I (perhaps ill-advised) have been adjusting them manually to account for this.
Is there a good reason why these colormaps (as opposed to magma, inferno, mako and rocket) don't have black as their darkest color?
