I agree about the website. It is beautiful but very dark and mildly depressing.

Agreed on the color scheme, the dark grey give me the impression I'm visiting a cancer survivor site or something similar. If your technology is aimed at improving people's health, you want to build up a positive, cheerful tone with your site, which to me at least would mean brighter colors.

I'd like to see the textures applied to the common red and white. Perhaps the hospital colors can be used while not feeling like you're in a hospital.

The more I think about it, the more I think the dark red makes me think of blood.
