Well, if you think the blue plus bulb is too white, you better be prepared for the purple plus bulb to be noticeably whiter visually. The purple plus bulb can really bring out some pinks and reds, though. I find it a bit overpowering in 4 bulb setups but many people love the bulb. You just really have to try different combinations. And be willing to keep a combination for a few days or longer to allow yourself time to adjust. People really gravitate to these super blue tanks nowadays, but I prefer to use the deeper blue look for a dawn / dusk type period and have more white during the day, as I think it displays the fish better and shows the true colors on corals.
Here is a picture of my rose bubble tip under a purple blus bulb to show you how that bulb can make some colors pop. As you can see, that bulb is definitely not blue looking. But who cares? It's about getting the blend you are looking for.
