Re-Apply color changes to my x-cart website

FYI, I have a contractor for this job pre-arranged so there's no need to bid on this project. Thank You. Re-Apply the color changes to my X-cart website. Only the colors need be changed ... an example of the color scheme I would like has been provided. I recently lost the color scheme on my site. If it should happen again I would like to be able to re-apply the colors myself. Please provide a list of every changed file and how that file was changed.
