As far as the plants are concerned, intensity is dozens of times more important than color spectrum. Either one of those bulbs will be equally adequate (or inadequate, in this case). Your problem is intensity. The P&A bulbs are some of the least "yellow" bulbs, so the tint you are seeing could very well be from the tannins being released from your driftwood, which is even further decreasing your light intensity levels.
Some low light plants might be able to survive in your lighting, but they will never thrive and grow. I strongly encourage you to try to get your lighting to around 2 watts per gallon.
