Is a very bold color. More towards the Royal Blue color. But not as dark. I have a pillow top mattress and it does cover the sheets. I would recommend looking at the thickness of your mattress if you have a Pillow Top to estimate if it would be a good fit for you. I bought a full size set. Which included 2 pillow cases , 3 decorative pillows and 1 comforter. Trim definitely covers the box spring. Also pillow case have room to fit a larger pillow
