FLORA
Quick environment exploration for Antilar.
The colors in plant life on this planet might be slightly limited. As the light emitted by the red dwarf consists of mostly red photons, the plant life would mostly be dark in color, almost black, purple or reddish.
The chemicals or fungi that would be present on the planet could have some different colors to still create a slightly different color pallet.
It might also be interesting to have some of the plant life to be 'alive' with subsurface scattering elements (see left tree).
The right tree would be a 'normal' tree.
Plant life would be able to grow very tall, as there is less downward pull. You would also see less leaves hanging down. Like with the grass, everything is very vertical, long and pointy.
