Rounding Text Color Values?

  • January 2, 2025

Hi everyone,

I’m back with another very specific request.

Someone on my team accidentally altered the colors of some text layers. We usually work with solid black (#000000) and white (#FFFFFF), but now some layers are slightly off (e.g., #0A0A0A or #FCFCFC). These subtle variations are causing issues with our stroke automation and are a nightmare to spot and fix manually.

Is there a way to automatically adjust these text layer colors to the nearest solid black or white?

I’m dealing with about 200 documents, so manually fixing them one by one, layer by layer, even with actions, isn’t really practical.

Any tips or solutions would be greatly appreciated. Thanks in advance, and happy new year!

One more point: 

If there are Type Layers that combine faux-black and faux-white text the Script in its current form would disregard that and use the color of the first letter/s. 

 

If this a likely scenario the Script would need some further amendments.

      It works perfectly, thanks!!
      I guess for the way it's coded it doesn't work in Grayscale images, which most of my documents are. So I set up an action that converts the document to RGB, runs the script and then converts the document back to Grayscale, so now it's working all good.
      Thank you so much!!!!

        I would not recommend that approach! (Maybe I am overly cautious …) 

        Adapting the Script for grayscale images should not be a problem, but I won‘t be able to do so today.

          Actions cannot make if-else decisions.

          Only a script can do that.

           

          According to the scheme:
          Document open - yes
          Text layers available - yes
          Loop through the text layers
          if text color values RGB below 128 128 128 -> 000 000 000
          if not,
          if text color values RGB above 128 128 128 -> 255 255 255
          next text layer
          Alert or save

           

          However, if only individual words or letter colors differ, the whole thing becomes much more difficult and complex.
