Thank you.
Ok, assuming i just have 1 diffuse map (image_map). How can i modulate this
image_map with a constant color with povray? I tried the "texture_map" with
all different modes but i could not manage to modulate all textures. I dont
want to fetch the pigment just from an image_map.
A really ugly workaround i can image of is to modulate the original
image_map with the color, save it to disk and give it povray to render. But
as i said, really ugly.

Example:

texture {
  average   // why not 'modulate'?
  texture_map {
    [0.0
      pigment {
        color rgb <1.0, 0.0, 0.0>
      }
    ]
    [1.0
      pigment {
        image_map {
          uv_mapping
          jpeg "texture01.jpg"
          interpolate 2
        }
      }
    ]
  }
}
