When I bought the bulbs I ordered 1 extra to play with the color, I do regret not ordering 1 or 2 more to play with....

The combination can be up to your liking when you have the extras..

I like the GE 65k bulb, and it's hella bright... Almost yellow but not... Read good reviews on it, which is why I ordered... But I had to take out the aquablue as it was very white with the GE, so I swapped in the AL 453 and it brought the color almost where I wanted it...

I would try
3 blue+
1 GE 65K or aqua blue special

Or
2 blue +
1 aquablue special
1 purple plus(another bulb I don't care for)but some love it..
