I've searched the Adobe forums and the web for ages, but am still unsure why this happens.
Here's the issue:
When I select the swatch in Illustrator, it starts off as 'book' (see attached).
Then, since I want the RGB values, I change it to 'RGB' (see attached).
Then when I look at the swatch book, I see that Illustrator's RGB is different to PMS swatch RGB (see attached).
So whenever I've created a CMYK palette, I have to manually make an RGB palette, typing in the values from the PMS book. This seems backwards and crazy for how advanced Adobe is in 2020. Am I missing something obvious here? Please halp if you have time, much appreciated! 🙂
