Eyes: Blood Angels Red Contrast, Gryph-Hound Orange Contrast
Hologram: Aethermatic Blue Contrast
Recess Shade: AK Black
The eyes get first a coat of Blood Angels Red contrast, followed by a more controlled Gryph-Hound Orange to add depth.
The hologram just gets an all over Aethermatic Blue - I love the effect of this paint, but I do find it often needs a couple of thin coats, as it is a very subtle shade at first. Also, I misinterpreted the base of the hologram as a device - if I were to do this again, I think I would do the conical shape in the same way.
Lastly, I felt some of the areas where colours meet needed some more definition, so a thinned down line of AK Black was run into them to really make the recesses stand out - this is most apparent on his face.
