Oh, maybe I should have explained those 2 keys…You can add a title for the color picker (context) and the color to start with:
const openPicker = {
_target: { _ref: "application" },
_obj: "showColorPicker",
context: "Some title for the color picker...",
color: {
_obj: 'RGBColor',
red: 0,
green: 0,
blue: 0,
},
};
const res = await photoshop.action.batchPlay([openPicker], {})
const rgbFloat = res[0].RGBFloatColor
