Coloring grass in 2.5

Ok, so as stated in the title I’m in 2.5 Alpha 2. I have the hair particles like I want them and stuff for the grass and I’ve set the amount of materials to 2 (1 for ground, 1 for grass). But currently I can only put a material on the ground even if I create a new material. How do I get to material 2 under material buttons so I can put a material on the grass?

Edit: Just realized this might be in the wrong spot, but it’s just a quick question that really anyone who’s had blender 2.5 for more than a day should know so hopefully it’s not an issue.

Just select the material for the grass particles


Oh, ok.
