I agree you have WAY, WAY to many reds. What ever possessed you to even consider that combo? That would be a very red or red/purple overall look in the tank. And you don't need any orange at all. Lots of blue and a little red (in the white leds) is for the coral. The whites are 95% for our eyes. Humans and corals see light very differently.
With 90 leds I'd have at least 60-70 of them in various shades of blue (420nm, 440nm, 450nm 460nm maybe a few 480nm), of the 20-30 that are left over, do all but 6-8 of them in a mix of white leds (cool, neutral and warm white). The last 6-8 do with equal numbers of red and green.
An be sure to keep the red and green leds next to each other in pairs. The red and green mix with the nearby blues and for our eyes create white light, but the coral still sees red, green and blue. With this combo I think you will have more than enough white leds (and RGB combos making white light) to have the overall look of the tank be 10K Metal Halide color temp (i.e. very white) when both channels are turned to similar power settings, which is what is best for your coral (lots of blue) and for you (enough white to make the tank look white even with lots of blue spectrum leds on). It doesn't take much in the way of white leds to completely over power the blue 'windex' look for our eye, but the coral zooxanthellae will still see a lot of blue which is what the coral wants.
You should look at this thread and take a couple of nights to read it over.

There are dozens of led layouts in there and in the past 6-9 months, many people, including me, have been leaning more and more to a 3:1 or even 4:1 blue to white ratio. Some fixture manufacturers are even playing with lights that have no white leds. They 'make' white by combining other colors, like the RGB combo.
