The rug colors are rich and vibrant.  After one week, it laid perfectly flat and is heavy enough to stay in place without a rug pad.  The predominant colors are red (more of a rust red) and a deep, dark blue.  The next most used color is more cream than yellow.  I had viewed the online photo quite often prior to making my purchase, but I was very pleased with the border detail I apparently missed.  There is a softly zig-zagged pattern made up of the most predominant rug colors on the inside of the outer red border that is repeated on the inside of the large blue border.  It really adds to the overall beauty and symmetry of this exceptionally designed rug.  I am very pleased with the design, weight and quality of this rug and the price was reasonable compared to others I considered at the big box stores and other online sites.
