The 55k is very yellow.But for that price it may be worth getting and upgrading to a 10k.The 10k has a very nice look by its self.Just my 2 cents worth.hehe
I have used the Hamilton 5500k bulbs with Pc actinics in the past with great results and growth. I don't know of other 5500k bulbs but the Hamilton's looked nice with a little actinic.
