The following code allows me to perform Histogram equalization but what I get is a GRAY Scale image, what I need is the RGBA/RGB image...

Tried merging but did not work. How to get the equalized color image as output?

function openCvReadyRGBA() {
            var img = document.getElementById("source");
            let src = cv.imread(img);
            let equalDst = new cv.Mat();
            let claheDst = new cv.Mat();
            cv.cvtColor(src, src, cv.COLOR_RGBA2RGB, 0);
            cv.cvtColor(src, src, cv.COLOR_RGB2YCrCb, 0);

            let ycrcb_planes = new cv.MatVector();
            cv.split(src, ycrcb_planes);

            cv.equalizeHist(ycrcb_planes.get(0), equalDst);

            //cv.merge(ycrcb_planes, equalDst);
    
            cv.imshow('canvasOutputRGBA', equalDst);
            src.delete(); equalDst.delete();
}

EDIT...

function openCvReadyRGBA() {
            var img = document.getElementById("source");
            let src = cv.imread(img);
            let equalDst = new cv.Mat();
            let claheDst = new cv.Mat();
            cv.cvtColor(src, src, cv.COLOR_RGBA2RGB, 0);
            cv.cvtColor(src, src, cv.COLOR_RGB2YCrCb, 0);

            let ycrcb_planes = new cv.MatVector();
            cv.split(src, ycrcb_planes);

            cv.equalizeHist(ycrcb_planes.get(0), ycrcb_planes.get(0));

            cv.merge(ycrcb_planes, equalDst);

            cv.cvtColor(equalDst, equalDst, cv.COLOR_YCrCb2RGB, 0);
    
            cv.imshow('canvasOutputRGBA', equalDst);
            src.delete(); equalDst.delete();
}
