Hello out there. I'm quite new to vue and was just working on a picture with a rather light evening sky. I added some stars and reduced brightness to about 10%, but unfourtunately Vue doesn't fade their light down as they come closer to the (bright) horizon as you would see it in nature. Does anyone know a trick to do it anyway (not in postwork but in vue)?

For anyone who wants to see my problem, I post a link to the pic. As you can see, the stars are always white, no matter whether they are high up in the sky or down at the horizon.
