Getting ready to order bulbs

How would a Giesemann PowerChrome 15K AquaBlue and an Aquaticlife actinic blue 420/460 bulb look in a dual bulb fixture? Would it provide good fluorescence from the corals as well as provide them with what they need to grow and be healthy? How blue would the tank be I am a little nervous that both bulbs being in the blueish range would make the tank extremely dark blue and be very dim and am looking for more of a light blue color overall. I could just use the aquaticlife 10k that comes with the fixture instead of the geismann but was looking to have better quality bulbs sicne everyone suggest ditching stock bulbs for ATI and geisemann

 

Placed the order, an Aquaticlife 36inch T5 HO dual fixture. Will have 2 aquaticlife blue/actinic 420/460 bulbs, an aquaticlife 10kbulb, an aquaticlife purple 460/620bulb, and a Giesemann PowerChrome 15K AquaBlue bulb. Hopefully some combo of any 2 will provide what I am looking for
