Yes agree with most said about color on flags.
I hate when I have to retreat 2 gens because I cant see which one is ahead.
I think you should revise the fairy fire when you are at the flags. I really feel cheated spending gems on a buff that does not really help finding the collies much.
On high levels with lots of buildings and generals - it is really not very helpful, just giving the collies a blue flag. The gens also have blue flags,- lots of stuff on the crowded island have blue color.
So please help us who does not have perfect eyes finding those collies. Fine to have a buff you need to pay for to get help - but then it really has to be helpful.
