and a lot easier against everything else... a blue/red blob is a lot easier to see.... don't see how you can possibly think it makes the game more challenging lmao.
I guess it depends on the tone of the color.
Bright, solid, blue colors are harder to see when they're strafing and jump so high that they're touching the sky. It
maybe harder to see against bright foliage.
Dark, red, solid colors
maybe harder to see on maps that have night skies and brick buildings.
Maybe yellow could be hard to see on very bright maps with bright foliage and bright maps like Battle at the Cinema.
I'm not sure about purple.
