Gabe,
What are you hoping to accomplish with oranges? I know reds are not what you ordered but visually you will be very hard pressed to see a difference between red and orange IMO. As a matter of fact I would venture to guess that orange will give you a worse look than red because orange has more yellow in it. This will give a more dull and brown look IMO. Put your whites only on then put on your whites and reds. This should give you a rough idea of what orange would look like.
Now if you are not a fan because of spectrum, how do you know how the corals will respond to it so soon? Also, if it is spectrum you are upset about not getting can you link us to any articles which specify orange is a usable spectrum?
btw - personally I love the look with the reds and blue/royal blues on. Such a neat intense purple look and fish really look cool!! Just my opinion though
