That's not exactly how I saw it:
First, I would suggest to rename the function since it's not really specific to tile highlights. Maybe evaluate_cosine_palette()? There are many more of those by the way: https://www.shadertoy.com/view/ll2GD3, in the future we could consider adding more as needed.
Also, I think this should be a free function instead of static method as it's not related to the ColorMap class.
Finally, it would be more logical to return a Color3f.

If we rename the method, those should be renamed as well (index, count sound good enough).
