Color book swatch libraries unable to recolor existing swatches with same name

When a spot color swatch's "display color" is defined in the "Swatch Options" palette, it does not recolor properly when the SAME named color exists in a color book swatch and is used to attempt recoloring. This is a serious bug in that an incorrectly colored spot colour swatch (including PANTONE colours) will display incorrectly and cannot be recolored. A workaround is to create the correct swatch in a new document and cut and paste the objects into the new document where the correctly colored swatch already exists. This bug exists in current CC 2017 and as far back as CS6 according to my tests.

See example corrupted display color for PANTONE 171 C

    For custom colors we refer to a *.ase file (swatches but not a color book) that has the correct LAB values and was created from custom ink drawdowns. If there is a Pantone colour that we don't have in a color book in Illustrator the correct LAB values can be referenced in our Esko Color Pilot and the correct colour can be "manually" represented.


    I see.

    A warning with options to solve a difference between identical named colors would be very useful.

    Another improvement would be that spot colors with a Lab definition and saved to a CC library, keep those Lab values (instead of being converted to CMYK spots).

    I did not see Car's post when I was answering.

    She has a good solution, just change the color back to Book color instead of Spot.

    Why is the color in your document a Spot color?

    It loses the connection to the Pantone Book version.

    Why would someone change the Book color to Spot and totally change the appearance of the color?

    A Book color can be seen as "locked", you cannot change it's name and color definition.

    InDesign has a different approach, it just looks at the name and will display the color correctly in Overprint Preview mode (as long as the name has not been changed).

    It's not entirely clear what steps you are using to see the issue you mention. Maybe you can write them down so that I can try to replicate.  If the issue is replicable, then definitely report it to Adobe using Illustrator Feature Request/Bug Report Form

    I tried two things to see if I could replicate what you are seeing based on the screenshot you included.

    Test 1 - Editing an existing swatch that was named with a PANTONE colour name, then turning it to a Book Color.

    Test 2 - Adding a PANTONE book colour and then merging duplicate colours.

    Test 1

    1. Created a New Swatch, named it PANTONE 171 C, and defined the colour using incorrect CMYK values, and applied it to an object.
    2. I then ensured the rectangle was no longer selected, and selected the swatch in the Swatches panel, and from the panel menu selected Swatch Options.
    3. In the Swatch Options dialog, choose Book Color from the
    4. As soon as you click OK, the artwork that previously had the green colour applied to it will be recovered using the Book Color. It will do so regardless of whether in the original colour definition you defined the colour as Spot or Process.

    Test 2

    1. Created a New Swatch, named it PANTONE 171 C, and defined the colour using incorrect CMYK values, and applied it to an object.
    2. Then add PANTONE 171 C from the Book Color Library, by clicking on the swatch in the swatch library, in the Swatch Conflict dialog box select Add swatches. Click OK. This will add a second PANTONE 171 C to the Swatches panel.
    3. Move this swatch above the green version in the Swatches panel.
    4. Then select both PANTONE swatches, and select Merge Swatches from the panel menu.
    5. The result will be that the previously green coloured object becomes red. You'd have to rename the PANTONE 171 C 2 swatch to PANTONE 171 C after that.

    Hi Cari

    Thank you for your detailed description. I did submit it as a bug too. My Illustrator behaves like yours and the problem does not occur if I follow your method.

    The problem occurs as follows:

    1.) Imagine my customer is working on a version of Illustrator that does not have one of the brand new Pantone+ colours.

    2.) Imagine that colour is PANTONE 171 C

    3.) Since that colour does not exist in their Swatch Libraries, in order to represent that colour in Illustrator, they create that colour in the swatches panel and name it PANTONE 171 C.

    4.) To more or less display that colour accurately in Illustrator they colour it with C100 Y100. This is a mistake but they don't notice.

    5.) Our customer supplies us this file and we notice PANTONE 171 C is incorrectly coloured.

    6.) We open the PANTONE+ Solid Coated swatch library color book and attempt to correctly re-colour the object with the correct PANTONE 171 C display colour. It does not work and does not ask us if we want to merge or replace swatches. So despite now having this PANTONE+ colour in my latest version Illustrator, it cannot re-colour the object.

    You are welcome to download the file link I made in my original post and test that file. There I coloured it with Lab instead of CMYK (same problem).

    We are now encountering this problem frequently (and sometimes not noticing if changes are subtle) especially since new PANTONE+ colours are being added in the manner I described above since they only exist in the very latest PANTONE swatch libraries.

    Did you try Cari's solution?

    Double click the color swatch and change it's Color Mode to Book color?
