You mean a WARM screen.

(1) Jailbreak so u can change display profile.

(2) Disassemble and change LCD in the hope, no guaranteed, new screen is cooler.

Both of which are not for the technically challenged.

Screens have variations, based on the manufacturer/plant. I witnessed this first hand. My original 4S had a very warm screen (yellow), when I got my 4S swapped because the sim door was effed, my new 4S had a very cool screen (blue). It really just depends... some prefer warm, some prefer cool. I prefer cool screens.
