    colors are often determined by what filters are used when capturing an image

    colors can also be the result of a galaxy's distance from us. The redder the galaxy, the more distant it is from us (the famous "red shift")

    it's the distance or the direction?

    distance: redder=farther away, blue/white=closer. direction means nothing.
