Randomize selected solid color layers always with (S > 25% & B = 50%)

hue need to be randomized?

#target photoshop

var s2t = stringIDToTypeID;

(r = new ActionReference()).putProperty(s2t('property'), p = s2t('adjustment'));
r.putEnumerated(s2t('layer'), s2t('ordinal'), s2t('targetEnum'));
var fill = executeActionGet(r).getList(p).getObjectValue(0).getObjectValue(s2t('color')),

with (color.rgb) {
    red = fill.getDouble(s2t('red'))
    green = fill.getDouble(s2t('green'))
    blue = fill.getDouble(s2t('blue'))
}

with (color.hsb) {
    saturation = 25 + Math.random() * 75
    brightness = 50
}
