You’ll want to look close at this picture I got last night.  Do you remember learning about the stars? And about the colors that they have are affected by how hot they are?  Yep. I still do, and when I turned up the saturation on this shot, I was SO excited to see the colors so clearly.  There are only a few red, a lot of blue, a few yellow & some that look more greenish.  Question, do you know what color is the hottest?
