Colour swapping in Xara 10.

[AndyD]

HI,
I am using Xara 10 and trying to change the colours on a web design preview jpg. I wondered if there was a quick way to change all the clue to a maroon? I am attaching the file I have at present. I have a friend who is an ex-Para coming to see me in a couple of hours and wanted to try and change the colour scheme on this before purchasing a web template if my friend like the colour change.
Many thanks
Andrew
