General overview of plant life
Compared to Earth, Abo vegetation (plants on Ged are often endemic) range from black to blue to purple-red in coloration.
This has to do specifically with the fact that both stars are red dwarfs. They are dim compared to the sun, thus plants need to gather either all possible specter of light available (black/dark violet) or from specific ranges or because they they simply never invented green chlorophyll or chlorophyll at all (blue, purple-red and red).
Bellow are the examples of earth plants of similar coloration:
Black/violet
Blue/violet
Blue/black
Blue
Purple/red
Red
Rule of thumb: The less light, the darker the plants are.
So, plants in Duskwastes are black and violet, Cycles lands have mainly red and purple, while Dayside have lots of blue with other colours here and there depending on biomes.
Blue colour comes from phycocyanin (it also has the side effect of being a good anti-venom). Red from - phycoerythrin.
Purple ones are more ancient type, relying on iolantophyll. On Earth chrolophyll-phototrophs evolved to take the part of spectrum not taken but more ancient retinol-phototrophs and thus are appear green (and use only certain and not the most beneficial part, not to mention that it's pretty narrow). On Marmakul the opposite thing happened. So lots of plants are purple or red.
Black plants are typically some variation of mentioned above with some adjustments, but there are true black plants that use iridiscentum. It's unique to Marmakul and basically allows plant to do photosynthesis on steroids, using all light possible for maximum effectiveness. This, however, has a side effect of being relatively costly energy-wise compared to all mentioned above. So given that they tend to grow in regions that are rather poor in resources, true black plats evolved to hunt, mostly in passive manner, akin to earthen jar plants or venus flytrap. But there are those who prefer active lifestyle, so to speak. Because if you want to survive on the edge of dusk, you must know how to spin.
But this is a story for another time.
Fair warning: evolution was drunk and high when she did some Marmakulian plants. Soon you will know why I'm saying that.
