So i want to create a planet that supports human life. Primarily, i would need to consider a star type, an atmosphere, foliage pigment, and potentially different types of plants. Think of it as a sort of alternative environment to earth in a way if it helps understand the question. Mostly everything else about earth would likely still apply, such as gravity, mass, temperature, etc.
Currently, i'm heavily interested in a foliage pigment that reflects blue light the most, giving plants a blue color. I also would be curious as to whether prominent fungi would be possible (giant tree-sized fungi, perhaps in certain areas in the planet coexisting with traditional foliage). I initially figured the star type would need to be an F-type star because that emits the most amount of blue light, hence plants would likely reflect that to avoid sunburn. Problem with that though is i don't have a good grasp as how that would affect human habitability or the sky color even (it would probably have to still be primarily oxygen and nitrogen to support human life).
I guess to put it simply - What would an earth-like planet's star-type need to be, sky color, how would fungi be affected (and would it be possible for them to grow to tree-like sizes), if the foliage pigments were to primarily reflect blue light and the planet were required to support human life?
