saving an excel document but color is missing

I went to business site that offers a worksheet they made in excel. This worksheet has some colored areas in it that are the working area of the worksheet. When I downloaded and saved it to my pc it was identical to the form on the website. When I went to the site to download it to my Sony VAIO laptop the color was missing from the form. When I copied the form from my PC which has color and downloaded it to my laptop the color was missing from the form. Both computers have the same version of Excel.
