Stars emit light in all colours (some more than others) but these combine and appear white to the human eye.
The night time ones
Humans see with color. Dogs simply have less cone receptors therefore they do not see light. Dogs only see in black and white.
Stars have a similar bluish white color due to the gases that are inside of them. When you see stars that are bluish white you know that they contain a lot of hydrogen.

Humans can see stars almost instantly after they look up at the night sky, as light from the stars reaches our eyes in a matter of minutes to millions of years, depending on the star's distance. However, the human eye takes about 20 to 30 minutes to fully adjust to darkness, allowing us to see fainter stars. This process, known as dark adaptation, enhances our ability to perceive the stars clearly.
