GE Helical 13w Yellow

I've always had good luck with the GE CFLs; I had lots of the 2700K version of this and they did exceptionally well for what they were, lasting at or probably well over the rated lifetime. By then I was switching to LED, though, and gave them all away. Well, now I have a more unusual version, a yellow one! Found at the Fred Meyer clearance section. Anyone else seen a yellow one? I've seen orange and bug light but not yellow.
