This should be a fairly easy question for the graphics people here....

I tire of punching in our company's brand RGB everytime I need it - is there anyway I can define it within the standard colour picker thingy?

Ta!

In addition, if there's anyway, (short of uninstalling them) to limit how many fonts appear in dropdowns - that would be awesome!

Oh and by the way this is Win7 64

I think with fonts, you do have to uninstall them. You can simply move them out of the Fonts folder. I used to love having lots of fonts until I realised they slowed down my computer ridiculously. I then went through the process of removing ones which were sufficiently similar.

When you mention windows pallette, is this in customising the UI?

No, just getting a colour into the custom swatches for all programs to use. I've worked out how to edit my application's .ini file to populate it, which serves the purpose I need (when in that program) but it would still be good to do the same for all applications in windows use - but so far every "howto" I've found on the web starts talking in code.... and I don't code.
