Quote - I focus on the stupid colors on the surounding page.  It draws my eyes away from the art.  Away from the products.  All I see is bright blue.. it's distracting!

The colours can be fix using the gallery stylesheet, although this doesn't apply to the window for viewing images full size as the user stylesheet isn't output in the HTML for that.  

Quote - I agree with nruddock.

My observations were mainly about the layout (the width in particular) and the "dumbing down" of the content, because as mentioned above colours are easily fixable where it matters most (forums and gallery).
Merchants are just going to have to suffer any ill effects stemming from a poor colour scheme in the MP.
