Is there any way to delete the light bounces without losing the illumination? I mean, can i delete or hide that 'white dot' on the image without losing the coloration made by the lighting? (I'm doing this on Blender Render)
This can easily be done by disabling the specular highlights of a lamp.
To do this, with the lamp selected and in the Properties panel, go to the Object Data tab (this is how it's actually called, but it's the one with the Lamp icon), and under the Lamp subsection uncheck the Specular checkmark.
