Yes. See: [Color Range: pick color in range base on values in a vector - #4 by stevengj](https://discourse.julialang.org/t/color-range-pick-color-in-range-base-on-values-in-a-vector/80533/4)

As explained in the linked post, doing linear interpolation like this produces a color map that is not perceptually uniform (distorts data).
