I wanted to chime in here that if I'd known of the color palette change, I also would have avoided updating. I used the pencil colors to avoid too many custom colors; that said, I need more variation in the colors for organization system. FWIW, it seems that on a Mac OS 11 (Big Sur) in light mode, the old colors still show up. However, they do not in dark mode. I can copy and paste the old colors too. So, for anyone who is on a Mac and trying to be able to see their old color scheme, try switching to light mode. However, this will get supremely annoying when it comes to creating new notes. I don't want to have to go into an older note to copy text with the font color I want just to use that color! Please please please bring back the pencil case of colors. Please.
