Colour palette and aesthetic design

[hanaral]

I've been messing with the colour palette and titlebar widgets, this is as far as I got:

I thought having orange would fit, but maybe it would be better to have the titlebar be flat white with the accents follow the sub's colour. I'd like to know what you think @xchan14

I think header bar should be neutral, either light or dark, then we can theme the widgets inside it. Let's use the palette from HIG provided by elementary team.
