How to change text color from red to white? I did a text animation based on this YouTube video.

When I render by clicking the animation button I get this.

My issue is I want to color the "A" and "P" text white (hex color - ffffff) and leave the "G" text red (hex color - ff0000) but I can't seem to find a way to do it.

Here is my blend file.
Go to top view (Numpad7) In edit mode select the A &amp; P text with box select. In the material tab add new color and change color white (fffff) and assign the material to the mesh.
