Got my 5000k's in today, looks good! They're more of a yellowish-white rather than a blueish-white, but it's very slight. To me they don't seem as prominent in direct sunlight as the 6500k's were, and I'm debating whether I prefer the color of the 6500k's more (had them on previously), but for now I'll see if they grow on me. Looking at BMW's newest cars with the LCI halos, they definitely have a blueish hue to them.
The good news is that the installation went a little faster the second time around
