Ooh I wrote that... Once you've computed the graph colouring then the Layer Style tab should be active, and that should have fields for Colour Scheme, Line Type, Width, and Line Colour. The Colour Scheme drop-down should give you a nice list of palettes derived from the ColorBrewer system. However the ColorBrewer palettes only supply palettes with a certain number of colours, and if your map can only be coloured with 23 unique colours then it may well be that the colour scheme drop-down is empty. When you hit the 'Compute Colouring' button it should tell you how many colours are needed. I suspect your map needs either only 1 or 2 colours or more than 8. I need to handle these conditions better. Patches for topocolour welcome. Source is in google code repo.
