Illustrator is changing my color values
I am having a very strange experience in creating artwork in Adobe Illustrator. I have some older files, specifically for one client, and noticed the colors were duller than when created. I wrote it off as me creating the files incorrectly many years ago. However, I recently updated to Creative Cloud and designed a new project from scratch for a new client with new colors. When I went back to that file today to expand on the project I noticed the colors were duller than previously. I compared some of the color values to the original artwork and noticed that they had been changed slightly (ie: RGB 67 > 67, 187 > 168, 219 > 200; 241>222, 172>153, 27>27; etc).
The files are, and always have been, RGB. It would appear as if my colors are being changed from the time I save and close, to the time I re-open. Any ideas?
