I have a text object and I want to change the inner color of it, so that it is black. How can this be achieved?

enter image description here

So the inside of the S is black, and the outside it still blue?

Like this:

I've already done it but there should be a faster way to do it.

What do you mean by inside and outside? – gandalf3 Jul 23 '14 at 6:03
So like this ( check edited question ) – Knuckles209cp Jul 23 '14 at 6:38

Blender doesn't have a direct way to do this currently.

Your options are:

  • Convert the text to a mesh, Then select faces and change their materials.
  • Use a shader which colors the faces differently based on their object space normal.

Ok , i made a duplicate and changed into mesh , the resized it. – Knuckles209cp Jul 23 '14 at 5:16

Here's a shader which does as ideasman42 suggests:

enter image description here

The values of the empty sockets in the multiply nodes are all 0.

This works by taking the dot product of 0,0,1 and 0,0,-1 in object space, and mixing two shaders based on the result.
In this case, parts of the surface facing in the +Z or -Z direction (in object space) will be black, while the rest of the surface will be blue.

Using a shader has the advantage of keeping the text editable as text.

Or you could make a World (or Object) space blend gradient ramp, play with the direction until it maps across the extrusion and then using Constant interpolation of the gradient ramp, adjust position of front face colour tab to be exactly on the edge of front face.
