Thank you, Iron Painter! The blue is indeed painted on, but it's showing up much bolder than in life. I blame the aperture setting I used for picking up so much of the color (f32). All of my hydra photos are a touch over exposed, too. They look much better in this photo: http://underthemountain.files.wordpress.com/2011/04/hydra-line-up.jpg
By the way, if you're curious, you can view the formula I used to paint this model on my blog:

Thanks again for the comment, IP!
I can't tell whether or not the blue reflection is painted on or from a flash... I think it's painted on. I think this figure is underrated. It's very well done, the sculpt is great, and your choice of metallic coloration is great. Love the retro feel too, well done!
