Truly Random Hue

I've spent the last few years writing my own plug-ins for Photoshop using Filter Meister. I have a rather strong background when it comes to manipulating various colour spaces. Imagine my surprise when I found out that SL and LSL are lacking when it comes to colour manipulation. The horror!

Been working on a rather bland project and needed to add some colour. The random colour scripts out there are seriously lacking for the blandness of my project. I need random colour and I mean *serious* colour. The generic random colour generators out there can generate pastels, darks, brights, and shades of grey. Those do me no good. What I need is random hue with tons of saturation. Since everything else out there seems to be lacking, seems like a good time to dip into my colour space manipulation background to learn more about LSL. After all, nothing says scripting like actually scripting.

I now have my very first script. It feels good.

It's based on the Hue <> RGB paradigm. Because of the ranges used in various places in LSL, takes advantage of bits. I don't know if it's elegant, but I think it's clever for my first script.

For a lot of uses, this is probably over-kill and probably won't be noticed. But it suits my purposes perfectly.

And it still feels good.
Cheers to learning LSL.
