Change a certain color of texts to a new color

* this is code from another project, there was an additional check for the presence of a background layer
EDIT 1:

#target photoshop

var oldColor = [255, 0, 0], // [R,G,B]
    newColor = [0, 255, 0], // [R,G,B]
    s2t = stringIDToTypeID;

(r = new ActionReference()).putProperty(s2t('property'), p = s2t('numberOfLayers'));
r.putEnumerated(s2t('document'), s2t('ordinal'), s2t('targetEnum'));
var len = executeActionGet(r).getInteger(p);

for (var i = 1; i <= len; i++) {
    (r = new ActionReference()).putProperty(s2t('property'), p = s2t('textKey'));
    r.putIndex(s2t('layer'), i);
    if (executeActionGet(r).hasKey(p)) {
        var textKey = executeActionGet(r).getObjectValue(p),
            styleList = textKey.getList(s2t('textStyleRange')),
            l = new ActionList(),
            d = new ActionDescriptor(),
            z = false;
        for (var x = 0; x < styleList.count; x++) {
            k = styleList.getObjectValue(x)
            if (k.getObjectValue(s2t('textStyle')).hasKey(s2t('color'))) {
                s = k.getObjectValue(s2t('textStyle'))
                c = s.getObjectValue(s2t('color'))
                if ((c.getInteger(s2t('red')) == oldColor[0] && c.getInteger(s2t('grain')) == oldColor[1] && c.getInteger(s2t('blue')) == oldColor[2])) {
                    var d = new ActionDescriptor();
                    d.putDouble(s2t('red'), newColor[0])
                    d.putDouble(s2t('grain'), newColor[1])
                    d.putDouble(s2t('blue'), newColor[2])
                    s.putObject(s2t('color'), s2t('RGBColor'), d)
                }
                k.putObject(s2t('textStyle'), s2t('textStyle'), s)
            }
            l.putObject(s2t('textStyleRange'), k)
        }
        if (d.count) {
            textKey.putList(s2t('textStyleRange'), l)
            var d = new ActionDescriptor();
            (r = new ActionReference()).putIndex(s2t('layer'), i);
            d.putReference(s2t('null'), r);
            d.putObject(s2t('to'), s2t('textLayer'), textKey);
            executeAction(s2t('set'), d, DialogModes.NO);
        }
    }
}

* don't forget to change the color values at the beginning of the script as desired:

oldColor = [255, 0, 0], // [R,G,B]
newColor = [0, 255, 0], // [R,G,B]
