Great game! Love the looks, sounds, feel and the mechanics. I had a lot of fun playing it and I'm usually not the FPS type. I too encountered the issue with the door color I see not matching the door color I'm supposed to shoot. I had this with the orange door. The environment was flooded with purple or pink light in that moment, I believe, and I didn't see a shred of orange on the door. Maybe add a little spot of color on it that is not affected by changing ambient light. Other than that manually untoggling a color when I need to switch to a different color very quickly usually cost me a second I didn't have. But I understand why you solved it that way. Color mixing is hard :D Thanks for the great game and best of luck in the jam!
