PC bulb question

Well after starting up my little new project. Ive decided that a 32w pc retrofit will be enough lighting for my 5.5g for zoas and some little lps here and there. I only have used t5's and halides, soo i dont know really what color a 50/50 bulb looks like and or a 10k for pc's. Which bulb would give a crisp white with a hint of blue?
