So after a weekend of testing with the colors, I have to say that the set you gave me is near perfection but can be improved!
I have problems with Green vs Black (Grey) on minimap.
Also your Yellow and purple vs the normal Yellow and purple are better but the normal ones are also okay
So I suggest:
Original:
Blue
Red
White
Yours:
Black (Grey it is great)
Orange (Burnt Orange)
Any of the two (original or yours):
Yellow
Purple
And Green is a problem. We need to tune green to be different from the grey black and different from the green of your city.
Original Green mixes with the Grey black, and your Green mixes with your city Green. (Only Minimap problem)
You could try something like this: #5BC236 Hex Color | RGB: 91, 194, 54 | APPLE, GREEN
Cheers.
Ps: Yes it works on winter (I had a couple of games and orange really looked cool at winter!)
