No.
Use something between the two, like a creamy colour.
Here's a tip to both of you in the future; NEVER use stock plain lights. They make the game seem ambient and saturated.
Also, GoW, no offence, but MUST you copy off other people? The end result is much more pleasing if you make something from scratch, and also, why would someone not just use the original mod rather than an FPSC game?
And before someone links me to it, I have made this mistake before.
