Bright light sped up, dimmed, turned red, then disappeared

Walking with dog in an open empty field, looking up at the stars. I fixated on one and it started to move slowly. I could tell it wasn’t the distance of a star now, had no idea how far away or large it was. It was a bright yellow/white circle. I noticed it was silent with no shadow of a craft behind it. I was thinking about taking my phone out at that point, but didn’t because I was afraid I’d miss something or it would go away. This was about 8-14 seconds. Then it slowly dimmed to a very faint pale yellow or white light then turned a faint red before it disappeared completely, that changing of brightness and color was about 5 seconds. The bus lot next to me has lights so that did make the pure night sky harder to see.
