Perhaps if the theme involved a variety of colours. There could be green, blue, purple, and maybe a little yellow here and there! I just feel as this is an artistic site, there sould be more than one colour to represent the scheme of things.
I'd prefer it if the colour was a bright colour in general. Maybe not green though. :/ And since it's an art site, I was thinking 'splotches of paint' everywhere would be better than one simple colour.
It would be nice if they changed the color once in while, after all we celebrate all sorts of holidays and events. I do like the color green for this site because it is very suitable but maybe trying out different colors couldn't hurt.
There should be 3 (or more, or less) options- DA green, obviously, and then a lighter color (probably not white that would look a bit weird with some people's art) and maybe a charcoal type of color so people could choose whichever they preferred.
Green is a color that calms you down when you're stressed, but I think the designers added a bit of grey to it so the deviations can look more colorful and attractive compared to the background, so I like it!
Green is not a creative colour. I'm kidding, I'm kidding... I just don't enjoy the green. It's very very dim to me. It's the colour for intellect, generally, but... Deviantart is, obviously, AN ART SITE!! I'd maybe prefer if each individual could change how they see Deviantart. This shouldn't be too hard, really.
I would prefer if we could customize it. If you just do it your selves and asked this everytime, you'd never get a full 100% yes. So yes you should find away for wither us to customize the there or use our own pics.
