Change Color of a part of the picture. How?

[erde]

Hi
I really looking for a solution how can I change the color of a part of a picture.
In my case it's a pharmacy sign (see attachment). I want to change the color of the white Part (snake&scale) into a sort of brown (#bcb29d).
The green cross I want to change into red.

I only managed (not even that perfectly) with hue. But I cannot choose exactly the colors I want. I manage with the color/select tool to select the region I want to change but then
I don't know how to move on.

Please I'd appreciate any help.

Redraw the symbol altogether. Then you can color it at will and can be resized without degradation for various purposes.

WD7 does not offer many options and Mike's suggest is best.

But attached is a simple if not as effective way to do this.

Ernst, here is a vector you can play with: Snake and Scales.web

Thank you all for your help. If I get it right, than I have to make this kind of color change in future with an another programm (e.g. Photoshop, gimp)? Unless I want to redraw my graphics.
Have a nice weekend.

The later versions of Xara let you select individual colors.

You could use this technique http://xaraxone.magix.net/PGD9/page%203.htm to mask the area then replace the color.

This is a very powerful tool.

Two steps. Select some of the green color with the Mask Painter Tool. Then Select the background color or colors with the Erase Tool. Press Erase Background.
