 All the logos uploaded to the Cloud Partner Portal should follow the guidelines:
 
 *  The Azure design has a simple color palette. Keep the number of primary and secondary colors on your logo low.

We recommend simple primary colors. If you're using a transparent background, make sure that the logos/text aren't white, black, or blue.
