Having both RGB and CMYK in swatches is a great advantage if you want to have a single document exported both to screen and print - but it turned out to be a swatch mess... what about a way to acknowledge similar colors as "equivalents" so we could replace entire document swatches from RGB>CMYK (or the other way around) when this export is needed? changing them individually will eventually cause mistakes.
and what about replacing entire link library from RGB>CMYK in order to export proper colours? I converted them and assigned all of their profiles in PS but now i must change all the links in the document (and all the swatches) before exporting - surely there's a workflow or a way around this...

There is big problem in InDesign for colours, because not every one remember different type of CMYK property .
Just take an idea so you can understand [ When you draw a owl in illustrator, so you have a lot of colours options to change by using colour helper or if need then add from swatches, it's that easy, but in InDesign that's very hard to that, because if you have to change colour then first you have to know that colours CMYK property, then you can add into swatches then you can use that colour. So that's the big different ]

Please help us to add colours in to only colour panel just same like illustrator.
We wait for your update.
Thanks

When you create or change a paragraph style, in the window where all the formats of the paragraph style are listed, you can change the character color, you can also create a new swatch by double clicking on the fill or stroke color icon. But once the new swatch is created, you can not imediately select it for your paragraph style, you have to change the category in the window (for example go to underline options), then go back to character color to use the new swatch.
Instead it should be that when the create new swatch dialog is closed, a refresh of available swatches appears in the list of character colors. By the way, in ancient Indesign versions this worked.

The Color Group function is really useful, but it only works in the creation phase if you select multiple colours. There's no obvious way to add a colour to a group after it's been created - there's no contextual menu option, there's no palette menu option, and seemingly, you can't drag and drop it into the folder, which is counterintuitive as this is something users do all the time with Layers. Similarly, color groups should function the same way inside the CC Libraries palette. There should be a shortcut to add any selected Swatch or Color Group to the current Library, with a warning if duplicates already exist (based on color value, not name); with option to keep separate swatches or replace with new one.

When deleting a swatch, it would be helpful if there was a way to change the default 'Replace with' Swatch of Black to be None/another color so one could option-click the trash icon instead of having to select None from the drop-down each time (or make None a merge-able 'swatch').

We get a lot of files where there are multiple swatches that aren't in use but don't get removed with 'delete all unused.' I don't think I've ever encountered a situation where I wanted to replace with Black anyway.

If there's a way to do that already, please let me know.

Thanks!
