If I could snap my fingers and change careers, I’d like to study lichen. It’s not that they are my favorite organism or anywhere near the top of the list, but rather I think they’d be endlessly fascinating to study and just as importantly, move at my speed. If you know anyone looking for a lichenthrope with no biological training and rather high salary demands, hit me up.
Their color is supposed to be influenced by their pigments, photosynthesis components, and how wet they are, but I suspect their favorite flavor of curry also plays a role. The lichen in the first picture clearly favors green curry, the greatest of the curries, while in the second we have fans of red and yellow. The gray lichen I assume understand that variety is the spice of life and enjoy them all.
