The colours of artwork shown on the site (on screen) may differ slightly to real life. I have checked the site looks correct on a bunch of different computers and screens and it looks pretty similar but not exactly the same on all.
This is due to differences in colours across computer monitors, screens have different settings etc...
Generally paintings look better in real life. More depth. Richer.
Either way - if for some reason you aren't delighted with your new piece, you can send it back (within 2 weeks) for a full refund, and good day to you.
