Well, a lot depends on the Kelvin rating for your bulbs... If you bought 6500K Bulbs, then they're going to burn more yellow... If you bought 10,000K they'll be a bit more blue, 15,000 even more so, and 20,000K being the bluest... Also, they do take some time to heat up and burn their true color... Give them a couple days to burn... Hope this helps...
