Issue:
Colour palettes not ending with white
Some of the new colour palettes end in white (after yellow). When this is used in a heatmap and Colour High is changed the heatmaps looks like it has holes (e.g. white in the palette is the same as the background). Could white be changes to very pale yellow?

Discussion:
I think this is a bug.
Also for Fire, Linear protanopic and Linear tritanopic.
