Carissa, from purely an optics standpoint, bulbs with a distribution such that they have a large percent of energy in the red end of the spectrum would bring out the red in these plants. This is simply because there is more red light for these plants to reflect. In addition, everyone's eye has slightly different sensitivity to colors and so while some color temp bulbs may look perfect to you, they might not necessarily look the same for other folks. Of course color temp has no real meaning in comparing different bulbs as it is some sort of averaging effect and is not really a true color temperature (like that for a black body radiator).

Whether different bulbs have the capability of bringing about color changes in the plants, more from a biological point of view, in that whether they would induce the plants to adapt and change their pigment/chemical constituents so as to better utilize the light from the bulb is a different matter and I don't have a good idea for whether this does happen.
