1) Download a colorset2) Look for it in your add-ons folder3) Open it and look for the colorset.txt file4) Drag it into the Colorset_Default folderI was told that Ephialtes is working on support for this, so this fix is temporary. :I
NOopen you console after downloading Colourset then say: canvas.pushdialog(RTB_ColorManager); into it.
