Request: a single hue variable

[CreeDo]

I almost feel like this could be done with like ten lines of code,
if only I knew what I was doing.

I already know about imagetint and ColorMatrix.
I'm thinking we could use those to create a new variable called Hue,
which would work like photoshop hue. It's a single 3 digit number,
starting at 0 and going to 360.

The effect I'm going for is to have something start
with a solid color, then as it gets repeated
a fixed amount of Hue could be added or subtracted.

For example the first line of text can be whatever, let's say ff000000 (red), and
each additional line is [Hue+30], so the additional lines of text in
e.g. my feed gradually cycle through the colors of the rainbow.
