I really do love them. The white has a bluish hue to them like an HID. I'm not sure how blue you want but a friend of mine settled for white because he thought he wanted blue but liked the blueish-ness in the white. But I imagine the actual blue is....very blue so if you want blue, go for it. Haven't seen blue in person though. This is how my white looks on camera:
In person, it's more white, go figure. Definitely a great mod. Even if you only got white, its so much brighter than the stock, single LED, halos. Good luck!
