Gradient colors

[nubbel]

It would be nice to have a method that generates color on a gradient between two colors.
API might look like that:

red.gradientTo(green).colorAt(0.5) // yellow-ish

I wonder if this feature should be available in this library or if an another library could not be more relevant?

I need to study the issue (if another people want participate it could be nice).

Moreover I don't think the fluent API is necessary in this case, I prefer something like that:

red.gradientTo(green, at: 0.5)

My two cents: gradients are a drawing operation, not a color operation as such. I think gradients are best handled in other libraries entirely. IMO, this (excellent) project should just focus on color.

[nubbel]

This issue is not about drawing gradients (we have CAGradientLayer for that), but about picking a color that lies on a point of a gradient from one color to another which has nothing to do with a drawing operation IMHO.

Indeed I don't think that "drawing" gradients is pertinent for the library. But building a gradient color array and / or picking a color from it can be useful.

For the next version of the library I've started to work work on but it needs to be involved and refined the API design.
