v@Cd = {1,1,1};
if (@N.y<0){v@Cd={0,0,0};}

This works perfectly thank you!

Go to material palette tab, find your material in one of the sub tabs there, select it then click the select button on the top most area of that window and it should select all objects with that material assigned.

Or just run this guys script here https://aboeinghoff.com/select-objects-with-this-material/ [aboeinghoff.com] It will create the option to just right click a material in tree view and click select objects with this material similar to maya.

Just like the title suggests, I would like to know if I can color points based on if their normal is facing a positive y value. Not sure how to write that in vex. So if its facing up its white if not then black. Thanks.
