Spray paint
The gun is not unique until it is
Short answer
Colour is a tell and a camouflage. Don't paint a flare.
Also: spray · paint
How it works
Spray cans recolour gear. Useful. Not a durability buff.
What to do
Match the woods you actually walk.
Don't
Don't neon-green a helmet for the VOD on a night you wanted to hide.
