By The Purple Grasses of Dantooine!

According to the Expanded Universe, Dantooine has steppes and savannas covered by purple grasslands, and we all know about the trippy color schemes of Felucian plantlife. The latest issue of Discover Magazine discusses the likelihood of lush grasslands on other planets having color palettes other than green. The article can be found online here. Here’s an excerpt:

[Astrobiologist Nancy Kiang] and her colleagues have used hypothetical star-planet combinations to predict extraterrestrial plant color with some intuitively jarring results. With a cooler star than our sun, little blue light would filter through an oxygen-rich atmosphere, so plants might have to rely on invisible infrared light for photosynthesis. Because they would reflect most visible light, they might appear white to our eyes. A hotter star could instead yield red or orange plants, though blue plants would be unlikely under any scenario, Kiang says.

Handy knowledge to have for gamers, designers and writers interested in telling tales of colorful planets.
