Let's say we have a Neptune like planet orbiting around a k5v orange dwarf star. The planet is about as massive as Uranus but its atmosphere contains a large amount of methane. Based on what I have read from other sources, methane is what gives planets like Uranus and Neptune its blueish colors. Distance from the star also plays an important role, since the more sunlight methane recieves the more orange in hue it becomes, which explains why Uranus is more greenish than Neptune. Now, my planet orbits a star with a luminosity of 0.17 and a temperature of 4,440 Kelvin. Based on this diagram:
I assume that most of the star's light shines somewhere around the yellow area of the spectrum (I am not sure, please correct me if I'm wrong) and so the radiance of the blue color would be much smaller than the Sun.
Amyways, to sum it all up, assuming the planet is about 26 AU away, what color would it appear?
