Hello. There is a binary star consisting of two stars, red dwarf and blue dwarf. The red dwarf has a mass twice smaller than the mass of our Sun, while the blue dwarf is smaller than the red dwarf. There is a planet orbiting around the binary star, at a distance, say, close to the distance between Earth and the Sun, which planet is similar to Earth, with similar atmosphere. Life, apparently, in my story, evolved there, where live aliens similar to humans. What color is the sky during day? (Additionally, what color is the sky at the sunrise and the sunset?). Thanks a lot.
