Need help with lighting

[50gTallnewbie]

So i recently bought a coralife 4ft dual bulb t5 fixture and im just trying to figure out what bulbs to buy i really like the blue look you get in stores but will that hurt my fish to not have white light i want the colours in my coral to look vibrant but still want my fish to thrive and corals to grow any suggestions all my google searches have came up with nothing for just a 2 bulb fixture

You could do one blue bulb and one white bulb. Corals will thrive under both, and that way the tank is well-lit while making the coral vibrant from the blue light.

The color won't bother the fish.
For ease, try the ati coral plus and blue plus.
One of each.
It the most popular combo.
And when it's time to change tubes if you wan more blue you can use one more blue tube. Less blue add one less blue tube like the coral plus.
