Object not reacting to blue/red/green lights (toon shader)

as you can see, the cube is only reacting to the point light (white).

Here you can see that the eyes are reacting to the red light (left eye reflection) and the green light (right eye reflection).
I just want to know why this is happening.
The texture for the turtle (not the eyes) i made following this tutorial:

Make the lights stronger and increase the radius?
