Hi everyone

A single .cr2 of 90s converted to .tif using GIMP 2.9 and processed using StarTools' oh-so-nice database noise reduction. Proper blue stars!

...and here is a stack with flat and dark-flat frames. The one above plus 5 more. Lost the blue completely. I give up!

Do you use DSS? If so have you tried: "Align RGB Channels in final image" both checked and unchecked?

Just read somewhere that people had problems with a specific setting in DSS screwing up color. Googled a bit and that setting was mentioned multiple times. I don't even use DSS myself, but figure it's worth a shot.
