Illustrator 30.6 - Unexpected change to swatch assignments

  • July 30, 2026

We have identified cases where Illustrator 30.6 may unexpectedly change color assignments after a file is saved and reopened.

The issue occurs when a swatch used by an artwork element is removed. Upon reopening the file, other artwork elements may be reassigned to different swatches.

I would like to know whether there is a way to make Illustrator preserve the original color values when a swatch used by an artwork element is removed, or whether this behavior could be a bug in Illustrator 30.6.

Could you provide some insight into this issue?

    Are you removing the swatch on purpose or does that happen automatically when opening the file? What kind of swatches are they? In what kind of artwork elements have they been used?

     

    Also: did you already reboot the computer and reset the ILlustrator preferences?

    Yes, the swatch was removed on purpose. 

    The swatch removed (Swatch 1) has these values:

    Swatch 1:
    Spot color
    CMYK    
    C0 M100 Y100 K0

    This swatch (Swatch 1) was used in a line object placed in a layer where there were no other elements.

    For more context, these are all swatches and layers in the artwork:

    Swatch 1*: Layer 1
    Spot color
    CMYK    
    C0 M100 Y100 K0
    *This the swatch that was removed

    Swatch 2*: Layer 2
    Spot color
    CMYK    
    C0 M100 Y100 K0
    *This swatch has identical values than swatch 1

    Swatch 3: Layer 3
    Spot color
    Lab color    
    L 20
    a 5
    b 5

    Swatch 1 was removed and all artwork elements still visually appeared with their original swatches, probably because the color values were cached in memory.
    After closing and reopening the file, some elements in Layer 3 were reassigned to 100% Black.

    Can you share this Illustrator file for inspection?
