color changing

[Username?]

I've remember a way to change only one color like red green blue or alpha.
It was like
e.this.color(0) = 1 for red
e.this.color(1) = 1 for green
e.this.color(2) = 1 for blue
e.this.color(3) = 1 for alpha

But that doesn't work
Does anybody know how to do that?

and does it work with other arrays like vel, too?

color = [blabla, e.this.color(1), e.this.color(2), e.this.color(3)] for red etc...

I use color := [1,0,0,1] for red, color := [1,1,1,1] for blue, etc.

I believe he wants to edit only one of the values in the color(RGBA).

I use color := [1,0,0,1] for red, color := [1,1,1,1] for blue, etc.

1,1,1,1 is withe -.-
