           Summary: CONDITIONAL FORMATTING: Color scales with non-rgb
                    gradients

Presently gradients used in color scale conditional formatting are rgb
gradients and it would be useful to also have the ability to use HSV and HSV
inverse gradients.

With HSV gradients we could have gradients like rainbow (3300FF to FF9900) and
with HSV inverse gradients we could have gradients like topo (4C00FF to
FFE0B3). Both of these gradients are color palettes found in R (

You can see the difference between rgb and non-rgb gradients with this tool
