Light bulb question

I have two frag tanks set up and mainly keep sps. On one frag tank I have a 250w de 14k Phoenix bulb. I really like the color and it's the bulb that I run on my main tank. The corals look really good under it.

I recently got a good deal on a 250w de Hamilton 10k bulb and I decided to get it and put it on the second frag tank to compare growth between the two frag tanks. I wasn't thinking about color and the frag tank with the Hamilton bulb looks bright yellow and imo doesn't look very good. I have no means of supplementing the tank with actinic or leds or anything, mainly because of $$.

So my question is, do I run the risk of loosing sps color running the Hamilton without supplementation? It sure seems like it from the yellow color of the tank. Will the coral just not look that good without supplementation? After firing up the bulb for the first time I instantly noticed some of the colors not "popping".

Would like to get some opinions.

Thanks!
