Colored Foamm??

[AdvanceDetail]

Hello MOL,

i had a wild idea about a foam gun i ordered it should be here this week, because the trip from Auto geek to chile is looonnnnngggg...

well my idea was to change the color of the foam, could this be done to change the "snow" from white to lets say green red or blue?

Before:

could look like this (but in individual colors) ?

now could that be done using colored pigments?? like food coloring? iam trying this as soon as my foamgun gets here, its just for a wow factor hehehe...:poke

I think food coloring could stain paint, possibly other parts.

Autobrite is coming with colored foam for the foam gun.

I would not try the food dye. Let the chemist come out with a safe color additive. Sounds like it would be fun.
