color prims by attribute

[elenvou]

Hello there!! 

I want to select all the primitives that have a specific attribute - @P = 0 - and assign a specific color to them. How can I do this in VEX or with nodes? 

cheers!!

P=Create a grid, drop Attribute Wrangle, set Attribute Wrangle mode to primitives:
 

@Cd = 0;
if (@P.x > 0){
    @Cd = 1;
    }

Here is we select primitives which have @P.x grater than 0. In your case, it would be @P = 0, but you would not see the changes on a flat grid that's why I modify initial task a bit.
Take a look at a VEX basics tutorial. Maybe it would be interesting for you.
