ok, well i actually kinda have 2. we have to make a made up galaxy, and i was wondering what color would be more appropriate for the sun (orange or yellow) and if i use yellow, would blue spots stand for the cold spots on the sun ? or would the cold spots be a different color ? if u don't get what i'm saying, then just leave a comment so i can explain it better

If I were looking at your galaxy project and saw blue spots on the sun, I'd think water not cold spots. Maybe white? I didn't know there were cold spots on the sun anyways.'

Well, since you're making it up, I suppose you can do whatever you want. Our Sun has sunspots, which are basically magnetic storms on the surface (photosphere) of the Sun. These regions are cooler than the rest of the surface, so they don't shine as bright as the rest of the surface. Sunspots actually shine orange or red, but since they aren't as bright, next to the rest of the photosphere they usually look black in photographs (unless you have a "closeup" image of one).
The color of a star reveals its surface temperature - the red stars are the coolest, then orange, yellow, white, and finally blue stars are the hottest. If you've ever used a bunson burner in chemistry, you've probably been told that the blue part of the flame is the hottest, hotter than a red flame. It's the same with stars.

The sun should be yellow and the sun spots should be orange or red due to the fact that red and orange are colder colors of light than blue on the spectrum of light scale.

In reality the sun is a star that is burning brightly. Which is why it looks yellow orange. I wouldnt have thought there were cold parts on the sun but maybe some slightly cooler parts.
But as you are making a made up galaxy why not make the sun purple? or completely blue. WHy does there have to be a sun?

If you want to get extra points, determine the age of the solar systems in your galaxy. Some stars (suns) will be cooler (red, yellow, etc) because they are older. Some will be white and blue because they are hotter.
You might even want to throw a black hole into the center of your galaxy to act as an anchor

A sun? Just a one sun galaxy? Are you sure you are not suppose to make up a solar system? Those can have one star. make it very big and very red, because red giants are such the rage. You can make them little white dwarfs. Some are blue! Black? Sure a dieing solar system with it's own black hole. Use two suns as in a binary system.
The cool spots on our sun are "black" and you can see these sunspots here:

Sun spots would appear orange, red, reddish black and black against a yellow star.
