How to get the swatch name in extendscript using fillColor?

[Arunkumar25715058ufpl]

Hi,

Now I using this way to get the swatch name using fillColor.

// Function to get the name of the swatch based on the fill color
function getSwatchNameByFillColor(fillColor) {
    var doc = app.activeDocument;
    var swatches = doc.swatches;
    
    for (var i = 0; i < swatches.length; i++) {
        var swatch = swatches[i];
        if (compareColors(fillColor, swatch.color)) {
            return swatch.name;
        }
    }
    
    return "No matching swatch found";
}

// Function to compare two colors
function compareColors(color1, color2) {
    if (color1.typename == color2.typename) {
        switch (color1.typename) {
            case "SpotColor":
                return color1.spot.name == color2.spot.name;
            case "GradientColor":
                return color1.gradient.name == color2.gradient.name;
            case "PatternColor":
                return color1.pattern.name == color2.pattern.name;
            case "RGBColor":
                return color1.red == color2.red && color1.green == color2.green && color1.blue == color2.blue;
            case "CMYKColor":
                return color1.cyan == color2.cyan && color1.magenta == color2.magenta && color1.yellow == color2.yellow && color1.black == color2.black;
            case "GrayColor":
                return color1.gray == color2.gray;
            case "LabColor":
                return color1.l == color2.l && color1.a == color2.a && color1.b == color2.b;
            default:
                return false;
        }
    }
    return false;
}

// Check if there is a selection
if (app.selection.length > 0) {
    // Get the selected object
    var selectedObject = app.selection[0];

    // Get the fill color of the selected object
    var fillColor = selectedObject.fillColor;

    // Get the swatch name based on the fill color
    var swatchName = getSwatchNameByFillColor(fillColor);

    // Output the swatch name
    alert("Swatch Name: " + swatchName);
} else {
    alert("No object is selected.");
}

Any alternative or easiest way is there?. Please help.
