Hi James
For your problem of generating the rainbow colours, I had a similar
problem wanting to automatically generate a fade between any two
colours. I do have uploaded an example stack to revOnline that creates
gradients. Unfortunately there's several quirks and strange
behaviours. Most are due to rounding error problems, but I'd wager
some are also due to bad coding.

I found a somewhat unsatisfactory solution to my earlier post
requesting a formula to translate color frequency into RGB color
coefficients. I found an image of the color spectrum on the web.
It was a rectangle ranging from red on the left to violet on the
right. By extracting the first line of imagedata I obtained the RGB
numbers for the spectrum. This list of 400 lines of RGB data was
inserted into a custom card property. As one draws out a line in the
Kaleidoscope the colors are drawn sequentially from this list so
that the line ranges (relatively smoothly) from red through the
spectrum to violet. It is not as smooth as I would like, but it was
quick and painless.
