Adding a new layer to an image

[avialonn]

Hi there,
How can I add an image on to another image?
I need to manipulate both images differently.
The first must be grayscale and the second (top) must be pink with opacity.
Anything I tried was producing the same results where the manipulation of the first image always override the second hence, the end image was a grayscale image.
I've tried both Composite and MagickImageCollection methods.
I'm on .net core 3.1 with Q16 any CPU.

I've tried this code with no success:
` using (var image = new MagickImage("C:\1.jpeg"))
{
image.Grayscale();
image.BrightnessContrast(new Percentage(15), new Percentage(5));
using (var overlay = new MagickImage("C:\pink.png"))
{
overlay.Alpha(AlphaOption.On);
overlay.BrightnessContrast(new Percentage(15), new Percentage(5));
image.Composite(overlay, CompositeOperator.Overlay);//also over
image.Write("C:\res.png");

        }
    }

However, I managed to get the result using the following;

using (var image = new MagickImage("C:\1.jpeg"))
{
image.Grayscale();
image.BrightnessContrast(new Percentage(15), new Percentage(5));
using (var overlay = new MagickImage("C:\pink.png"))
{
overlay.Alpha(AlphaOption.On);
overlay.BrightnessContrast(new Percentage(15), new Percentage(5));
using (var outputImage = new MagickImage("C:\1.jpeg"))
{
outputImage.Composite(image, CompositeOperator.Over);
outputImage.Composite(overlay, CompositeOperator.Overlay);
outputImage.Write("C:\res.png");
}
}
}`

I'm sure there is a better way of doing this.
Thanks

Can you also attach your images so I can see what you are trying to do?
