Update I have created a CSS template with all of the political party colours here

After spending about half an hour trying to find a site that detailed all of the main UK political party colours with no avail, I decided I would knock my own one up;

Party Main # Main RGB Secondary # Secondary RGB Typeface Conservative and Unionist Party #0087dc R:0 G:135 B:220 #6ed700 R:110 G:215 B:0 Lucida Sans Liberal Democrats #FDBB30 R:253 G:187 B:48 #00929F R:0 G:146 B:159 Arial Labour Party #d50000 R:146 G:0 B:13 #9B301C R:146 G:0 B:9 Bliss Scottish National Party #FFF95D R:255 G:249 B:93 #0A2C50 R:10 G:44 B:80 Helvetica Plaid Cymru - Party of Wales #3F8428 R:63 G:132 B:40 #e1cc00 R:225 G:204 B:0 Helvetica Green Party of England and Wales #008066 R:0 G:116 B:95 #8dc63f R:162 G:189 B:48 Frutiger Light UK Independence Party #EFE600 R:239 G:230 B:0 #B3009D R:183 G:0 B:157 Arial

Feel free to edit and add the other parties,

Cheers,

Rich.
