Adobe Illustrator changes the colours of my document

[Stefan285521505f3p]

Illustrator changes my brand colours in my documents after I save and close the file. At reopening the colours a bit darker, for instance it changed one from #42d9de to #42c2c7 and doing this for all the colours in my brand manual. The files are setup as an RGB files and this happened on 2 different machines, one setup with fresh OS and clean Creative Cloud install. Any ideas how to solve this? Thank you!

Is your color management set up correctly? WHich color profile do you use for the file? Are they in line with your working profile
