Oddity using the tab key in the 'Color' window

Hello all

 

This has started happening a short while ago. If I want to change the CMYK values on a colour in the 'Color' window and change the C value, then tab to M and change that, when I tab to Y the whole set of percentage values goes blank and the color preview has a question mark.

 

Example:

I change 40% in C to 50%, then press the tab key to move to M, then tab to Y to change that, everything goes very odd - screenshots attached...

 

Is this a bug? Been using Illustrator since Illustrator 3...not something I recall coming across before.

Apologies for the delay in replying to Ton's suggestion, but I've just posted on the UserVoice link.

FYI I've attached  the screen recording I posted.

 

Thanks

Hi @wwrsimon,

 

Thanks so much for sharing the screen recording and details. I tested this on the same Illustrator version, 29.8.2, and the color fields in the CMYK palette update normally when using the Tab key. However, I don't see the values reset or the color preview switch to a question mark.

Since this happens consistently for you across files, it might be linked to a specific app preference or color management setting. Could you please try manually resetting Illustrator preferences once and see if the issue still occurs afterward? You can back them up before resetting if needed.

 

Please let me know how it goes after that.

I have the same issue. For me the problem seems to be related to the palette being on my second monitor; once I drag the Color palette on to the primary screen, the behaviour reverts to standard practice.

Illustrator 30.4

Mac Studio M2 Max

MacOS 15.7.7 Sequoia

Both monitors connected via USB-C/Thunderbolt, both connected directly to USB-C/Thunderbolt ports on the Mac; no USB hubs involved (in that chain, anyway)

No issues with InDesign or Photoshop using much the same layout of palettes etc

Hello ​@MattFondu 

 

I’m sorry to hear you’re having similar trouble with Illustrator. Would you mind trying to update your OS/Illustrator to the latest versions to see if that helps resolve the problem?

If the problem persists, we’ll need some more information to be able to help you with this scenario:
 
1) System Report
- You can generate it from the Apple icon > About This Mac > System Report > Save to the desktop.
 
 2) A brief screen recording of your workflow and the problem

Kindly upload the files to Google Drive/Dropbox/etc. and share a public link here or via DM so that we can investigate this further.
 
Looking forward to hearing from you.

A further oddity - I just opened the document again and Illustrator now thinks that swatch is 40% cyan/20% magenta/100% yellow/0% black, which clearly it ain't...

Hello @wwrsimon,

Thanks for reaching out. That does seem odd. Could you confirm the exact version of the OS/Illustrator installed, if this happens with all files, and a small screen recording of your exact workflow, so I can better assist you?

Looking forward to hearing from you.
