How green is your Tory?

Blue has been the colour used by Tory MPS in promotional materials for many years (red being Labour, yellow for Lib Dems). However more and more Tories are using the colour green - largely associated with the Green Party! Additionally a recent social media study found 70 Tory MPs out of 98 failed to indicated they were members of the Conservative/Tory party. Are they seeking to dupe the public in the forthcoming elections by 'dropping' association with their party!
