Select the white by color.  Choose foreground color to be black, chose 
the 'fill with color or pattern' tool (looks like a bucket) click mouse 
on the white background, it will turn black.  While it's still selected, 
choose the invert selection, change foreground color to white, click 
mouse on one of the tan lines.

Understand, if there is any variance in the colors, the change won't be 
100%.  In such a situation you could use the 'select contiguous regions' 
tool.
