I don't use camo. Never saw the need for it.
Texas not so much, hunting the mountains, if it buys you 5 more seconds as an elk or Mulie deer is looking at you, that maybe all you need to get an arrow in the boiler room.
With that said I hunt in solid colored pants out west a bunch but my shirts are camo.
But for me the clothing needs to meet the techincal aspects.
Hot- breathable and wicking
Rainy- waterproof or great DWR
Long pack in hunt- repel human stink factor for more then two days.
