Due to at least one of our users being colorblind, I have taken the time to compile a small zip file containing a "config" folder, than you can drag and drop, or extract, into your "tekkitmain" folder to overwrite your existing configs with options for colourblindness turned on. Please note, any custom configurations will be overwritten, however if you are making custom configurations, I'm assuming you don't need this The file can be found in the tekkit channel (file browser) and at http://tekkit.pr-gaming.net/files/Tekkit_Colorblind_Config.zip
