I was wondering if it is possible for a photoshop action to choose foreground or background color from the swatch. I have tried doing it, but instead of picking from swatch it is always taking a fixed value. I am trying the script to pick color from the swatch sequentially. For example, if there are 5 colors in the swatch, it should pick 1st, 2nd ...upto 5th color.

  • How easily / often do you need to update the colors you want to cycle through? Given that it looks like getting a swatch color is tough, if not impossible, I made this script as a sort of a test.. Also if you didn't know already, you can set a shortcut key to launch a script. – Joonas Oct 20 '15 at 12:50

You should be able to do this in script. Tom Krcha has a script which you may be able to adapt (Add A Color To Swatches Panel In Photoshop Using ExtendScript/JSX):

var red = 255;
var green = 0;
var blue = 0;
var name = "Red";

var addColorDescriptor = new ActionDescriptor();
// Get reference to Swatches panel
var swatchesPanelReference = new ActionReference();
swatchesPanelReference.putClass(stringIDToTypeID('colors'));
addColorDescriptor.putReference(stringIDToTypeID('null'), swatchesPanelReference);
// Setup a swatch and give it a name
var descriptorSwatch = new ActionDescriptor();
descriptorSwatch.putString( stringIDToTypeID('name'), name);
// Add RGB color information to the swatch
var descriptorColor = new ActionDescriptor();
descriptorColor.putDouble(stringIDToTypeID('red'), red);
descriptorColor.putDouble(stringIDToTypeID('grain'), green); // grain = green
descriptorColor.putDouble(stringIDToTypeID('blue'), blue);
// Add RGB to the swatch
descriptorSwatch.putObject( stringIDToTypeID('color'), stringIDToTypeID('RGBColor'), descriptorColor);
// Add swatch to the color descriptor
addColorDescriptor.putObject( stringIDToTypeID('using'), stringIDToTypeID('colors'), descriptorSwatch);
// Send to Photoshop
executeAction( stringIDToTypeID('make'), addColorDescriptor, DialogModes.NO);

  • Thank you very much ! How can I pick color from swatch using script ? – S.M. Oct 20 '15 at 7:20
  • @S.M. The script: "Add a color to swatches panel in Photoshop". I'm pretty sure KJP meant this script as a starting point. It's not a straight up solution, as it does the opposite of what you want. Although, I have to ask. Let's say you have 10 swatches. how did you plan to choose what swatch to use? – Joonas Oct 20 '15 at 7:34
  • @ Joonas. Thanks for your reply. What I am really trying to achieve is, pick colors as foreground sequentially. Lets say I have 10 colors in swatches. I am trying to pick 1st, 2nd, 3rd... upto 10th. Is there a way ? – S.M. Oct 20 '15 at 7:38
  • @S.M. You mean like: press a hotkey once: Swatch #1 gets selected as the foreground color, press a hotkey for the second time: Swatch #2 gets selected as the foreground color... etc? – Joonas Oct 20 '15 at 7:40
  • @ Joonas Yes . Like a loop. It will choose swatch#1 do an operation, and choose swatch#2.. and continue until it have picked all colors in the swatches. – S.M. Oct 20 '15 at 7:44
