Depends how the template was made but if the background is a picture then you
wont be able to change the colour in powerpoint except maybe by placing a
coloured semitransparent shape over the master. If you have access to
photoshop or similar you can save and change the background picture (right
click > save background)

Did that answer the question / help?
