Making pollution map more clear.

[Artman40]

Currently, pollution map in this game shows pollution area in red gradient. This makes the edges of pollution a bit difficult to see as these are shown in faint red. My suggestion would be to change the pollution map as following:

Areas with no pollution would be shown green.
Edges of polluted areas would be shown yellow.
The most polluted areas would be be shown red (as they currently are) with orange gradient between red and yellow.

That could make the extent of polluted areas more clear.

This would be helpful, especially when figuring out what biter spawners are being polluted and attacking you
