If your looking for a little blue without adding supplement lighting and sticking with all hamilton setup go with there 20k bulbs, 14ks have run anywhere from white with a tad bit of yellow to white for me.
For me using hamilton setup.. 250w Cayman pendants, hamilton m80 ballast and 14k pheonix 250w bulbs. Still on the whiter sde of things with a blue hue. I am looking into something something that will add some actinic blue for the colors to pop. Pheonix14k has some blue color but not a actinic like blue, some colors seem to get washed out, some reds, yellows, and greens look a little pale in color for me but still show quite well.
Next trying XM20k bulbs to see if that makes it better before adding actinics. If that doesnt work then adding actinics. Would have been easier just going with galaxt ballst with radium bulb (SE bulbs) I could just get new reflectors/sockets and use radium but hamilton m80 ballast i have burns them whiter than a galaxy but you still get actinic pop from the bulbs.
