Thank you for the kind words.
I actually 'borrowed' the idea for blue from here:
I used Vallejo model color "Dark Blue" and added the highlights using the same color with a little white added. I tried to add spots of highlights at the top of the bottle and where the bottle slopes.
After dull coating, I went back and painted the bottle with Vallejo Gloss varnish to help emphasize the 'glass look."
