Light color texture

[Tipiizor]

I've got a quick question.
In canyon you can set a light block and change it color. When you do that, the texture (ArenaLight i think) is colored too.
Is there a way to do that too (not painting in editor, but just have the colored texture) on custom item actually or its hardcoded ?

Thank you.

Are you sure the texture itself change color or it's just the diffusion of the color of the light block?

I'd like an answer from dev member of nadeo to be sure, i tried to project a light (spot and point) in the direction of this texture, but the result is not like nadeo's
