Star Question

On the left side of this photo it seems to me that there are three pairs of stars in dual star solar systems. The one set on the bottom left seems to be side by side and emitting yellow and blue light from both a yellow star and a blue star. The next set of stars or at least what seems to be the next set just looks like a blue star however there also seems to be yellow light coming from this star as well so maybe the yellow star is behind the blue? And then the last set of stars at the very top seems to be the exact opposite as the second pair by showing a yellow star and also having blue light being emitted which again could be a star behind the other. I'm just wondering if anyone can tell me more about this picture as well as just any tips they have about the cosmos.

Binary stars are so close together that they appear to be the same star. The actual size of the star is smaller than a pixel, and the light spreads out around it. So these two stars are widely separated, so it is unlikely to be a binary system. One may be much closer, it is difficult to know.

As for the colours of the other stars, stars usually produce diffraction spikes, which is caused by the internal wires in the telescopes. Different colours are affected in different ways, and the colours get separated.
