Theme setting to change colours

Hi there,

I'm currently working on an Omega subtheme with a settings tab that allows it to change the colors of the theme; like an inbuilt, more modern and more lightweight Color module. However I'm stuck at a point where I'd need to make sure upon enabling the theme that a color.less (LESS css preprocessor, awesome stuff!) file exists somewhere...

• option 1: putting the colors.less into the theme's css directory; would be my preferred solution for it would all be in one place. However I can't figure out how to save files to another directory than in one of the stream wrappers (like public://). Have tried writing a stream wrapper but that didn't work out (because of the limited hooks available from within a theme?)

• option 2: putting the colors.less somewhere under public:// is probably the cleaner, more "drupalesque" way but I'm running into two issues here: first I'm not sure how to safely load it from within global.less (which I would have to do to have all the less variables from colors.less available). Of course I can do
import "../../../../default/files/color_settings/css/colors.less"; but that doesn't look right at all. What if anything doesn't sit where I have it?
And second how can I make sure that colors.less is there/gets created when my theme gets enabled? I've googled my ass of, but couldn't find a hook or anything for that o.O Am I blind?

Or is it not a good idea at all to have it inbuilt? I just thought this for a base of premium themes that just have to be downloaded with omega; enable and go, without installing and configuring heaps of other modules. Could I write a module included and enabled with the theme anyhow? (Without install profiles or make files – I thought making it almost as easy for them as Wordpress). Any hints thoughts on this would be greatly appreciated!

Cheers, Tina
