[support] OT: color swatches for drupal

[Luke]

Hello

This is probably OT, unless there is a Drupal way to do this.

For a client, I am designing a Drupal and UC based site.  Some of the 
products require the buyer to choose a color from a specific range (think 
carpets and such).

On their previous hand-coded site, they had a little tool into which they 
could enter a hex RGB value, and the site would show the color (one for 
each color option).

I was thinking that a better way might be to provide a gif or jpg image 
for each color, using the UC option images module.

However, how to generate those images, which would essentially be little 
blocks of solid color, is the question which is plaguing me.

Surely this is not a unique problem.

I found closed source Windows based programs (ColorImpact, for example) 
which claim some such capability, but not only does that seem like 
overkill, it seems as if there should be some simple way to go about this 
using an open source option.

Ideas?

Thanks

Luke
