Scott - So this is my Librarian  from the Space Hulk box, set to be in my Blood Angels army.
The blue is as follows -
Layer 1 - 2/1 Kantor Blue/Chaos Black
Layer 2 - Kantor Blue
Layer 3 - Caledor Sky

The last stages will be a thin wash of Drakenhof Nightshade followed by a final highlight of Caledor Sky and P3 Morrow White mix. Can't wait to get this one done!
