"You should have picked PANTONE 628 the CMYK process build, or the RGB Hex version if it wasn't a spot colour job"
To be frank, I don't know what the hell any of that means. But why should I have to? Why should I "suffer" because I don't know a bunch of gatekeepy factoids about the real-life differences between PANTONE 628 and B7DDE1? "Oh, sorry honey. You know that wedding invitation design I made last week and showed you? Well that's gone now, because I entered the colour we liked in the wrong format. It's my fault though. I used a colour palette intended for spot colour printing. What a goof! I am rightfully being punished".
Don't you see how this is insane? I can see a colour I like in real life, and see that there is a tag associated with that colour. I can tell that tag to a piece of software that I pay for, and have the software return a result I like. Then that software can, out of nowhere and without warning, decide to tell me "Oh, I'm not going to show you this colour any more". And then I'm expected to say "Oh, that's reasonable. I should have understood that the colour entry field I used was subject to cancellation, and only intended for spot colour for printing on coated stock".
