Another option is setting the Colors at game.cfg file:

Also, you may try lowering the in-game graphics and observe.

Enable Low Specifications Mode
Enabling this will reduce visual fidelity in certain areas of the client but may significantly improve performance. We recommend enabling this options if you're experiencing stuttering or lag when using the client.

At Client Settings > General Tab > Select "Enable Low Spec Mode"

Close Client During Game

Enabling this will close the client to improve in-game FPS on low-spec machines. However, it will significantly increase the amount of time it takes to return to the scoreboard screen at the end of a game. We recommend enabling this option if you have a low-spec machine and are experiencing very low FPS in-game.

At Client Settings > General Tab > Select "Close Client During Game"
