I know a lot of modern games have started to include a color blind mode. Alternatively, SE could just do what the government has done with traffic lights. Make "green" a bluish green teal and "red" a yellowish red orange. Teal/Orange would look cooler anyway ;P But yeah, other than that like many others have already said, a lot of parties now prefer to burn down the closest sister regardless of color. It's a really good point to raise for future content development though.
