Plasma Color Palette
Description
Examples
The Plasma color palette is a sequential colormap by Nathaniel J. Smith and Stefan van der Walt. It is designed to be perceptually uniform even when viewed by persons with common forms of color vision deficiency and when printed to black-and-white.
withColorTools:
In ColorTools we provide a 256 color version of the colormap.

You can reference colors in the palette by number in most commands that understand color names.
plotx,x3,x=−1..1,color=Plasma 30,Plasma 170
C≔ColorPlasma 100
C≔⟨RGB : 0.678 0.153 0.576⟩
You can programmatically access the colors using ColorTools commands.
P≔GetPalettePlasma:
P1
⟨RGB : 1⟩
SwatchesP
Plasma is best used to construct as a sequential gradients from dark to light and from blue to yellow via purplish red.
ColorTools:-SwatchesP,mode=gradient
This colormap is good when converted to grayscale.
ColorTools:-SwatchesP,mode=gradient,`=`filter,c↦ColorGs,c
This colormap is also reasonably good for users with CVD.
ColorTools:-SwatchesP,mode=gradient,filter=CVDSimulation
The Blend command can be used to create a function to color arbitrary ranges. It can take the name of a palette to generate a colormap.
ColorMap≔ColorTools:-BlendPlasma:
ColorMap0.35
⟨RGB : 0.632 0.109 0.608⟩
And is particularly good when used to color surfaces. The colorscheme option of plots can take the names of palettes to generate gradients.
plot3dsinxcosy,x=−32π..32π,y=−32π..32π,colorscheme=Plasma
