I bought the Morimoto GMC Sierra Spec kit 5500k 35 w kit and it is a pure white. No blue what so ever. I think the 6500 would be a little more blue. My brother got the spec kit as well with 4500 kit on his 2014 Sierra all terrain and it has more of a yellow tint. Side by side mine appears brighter because its more white but thats my opinion. I just think if I would of gotten the 55w it would be alot brighter but it wouldn't last as long and the warranty isn't as long with the 55w.
