[Tex/LaTex] nice color scheme generator for beamer(poster)

beamerbeamerpostercolorthemes

There are plenty of palette generators for the web, e.g., Color Scheme Designer . Among other stuff it can export schemes in XML. Is there a nice XSLT to convert it into STY file that I'd use with beamerposter? The caveat here is also that that generator uses RGB and not CMYK model.

I understand I can manually code all the stuff as I want like

\setbeamercolor*{normal text}{fg=tachameleon, bg=ta3gray}

Or are there other easy ways to create pleasantly looking themes?

I have a feeling that most of the themes are crafted by hands? Am I wrong?

My university (UCL) has a style guide and guidelines for the colours that should be used in all publications (i.e. a corporate identity). I found this to be a good place to start in selecting colours for a student poster. Style guides will (hopefully) have been designed by graphic designers who should know which combinations of colours work!

I created a colour palette (which I've included below), and then referred to this using \setbeamercolour commands in a .sty file.
