Help ID Flat Wound Stings on a bass I just bought

[ClassicJazz]

Just picked up a used Fender Sting Signature P-Bass. I really like the flats that came on it, but not sure what they. They have blue windings on the ends. Can anyone ID these? Thanks!

Edit: D'Addario Chromes. Didn't think to look at the string balls. Definitely D'Addario strings.

Ok, Chromes. I didn't think to look at the string balls. Definitely D'Addario strings.
