I'm designing a world orbiting a red dwarf. Now, I want the life on my planet to have a rich variety of color just like life on earth does. The problem is that I don't know if that's feasible. From what I understand, on Earth the Sun's light shines mostly in the visible spectrum so life on Earth has adapted to see in it and organisms make use of their colors for various purposes like camouflage, warning or sexual attraction. In the case of red dwarfs, I've learned that they mostly shine in the infrared spectrum. So does that mean that life on my planet would only see in the infrared spectrum or could they see in the visible light as well. If they only saw things in the infrared does that mean that they wouldn't need to display any of the colors we see? If that's the case, how can I avoid that?
Edit: I should clarify that when I say I want there to be a variety in color I mean that from a human's point of view. Why would creatures on such a planet evolve to display various colors in our field of vision when they themselves can't see on the visible light spectrum (I am only assuming that they can only see on the infrared because that's the dominant light emitted from red dwarfs. If it's possible to see in both fields of vision please correct me)
