Different color icons for variable per type

We have global scene and object variables which all have their own icons
Problem is that they are all blue/white more or less

I would suggest adding to them colors so it is easier to users spot the difference

Since global is globe it could be green
I would leave scene blue as it is
Object could be anything else
But that are just my ideas for colors
They could be anything as long as color would give clear indication which variable is which
In other words each colors used for icon should without a doubt be so different from other two so user could without a problem tell them apart

I would even go as far as to change icon on the left which says Var
To match color of variable icon
