Your pic shows that they are grey, just like in the threads below. They are no where near blue.Bought these 2 months ago. You can see H&R written on the springs. Dark Blue, but a little hard to tell in the pic. Not saying Eibach isn't blue as I have no idea. But H&D sport springs for a 2007 M5 are dark blue.

Had mine in hand and were not grey. Dark blue in my opinion and I'm not colorblind.
