I used 2 jungle dawn leds on this, there's other options for plant lighting though... the JDs are a bit pricey.
But yeah, there's tons of options for colors, just depends if you have the lighting for it. Bromeliads, cryptanthus, caladium, jeweled orchids(as ground cover), and nepenthes were some that I used in my enclosure to make it pop.
Wandering jew are pretty colorful and happen to be very easy to keep. Most others with out of the ordinary colors need the light. Also usually takes good lighting to get plants to flower.
