C# Color an image with shadows

Question

I am currently creating sort of a game with C# and am trying to create outfits for the players. I would like to make cloth design and let players chose the colors.

You could iterate over each pixel of the bitmap and make a color shift in the direction you want. When I say colorshoft I mean a you have to adapt the RGB values of each pixel.

A simple shift to red could look like this:

for (int Xcount = 0; Xcount < myBitmap.Width; Xcount++)
{
    for (int Ycount = 0; Ycount < myBitmap.Height; Ycount++)
    {
        //get color of the pixel
        Color pixelColor = myBitmap.GetPixel(Xcount, Ycount);
        byte red = pixelColor.R;
        byte green = pixelColor.G;
        byte blue = pixelColor.B;

        //make shift and prevent overflow
        if (red < 205)
            red += 50;
        else
            red = 255;

        //set color of the pixel
        myBitmap.SetPixel(Xcount, Ycount, Color.FromRgb(red, green, blue));
    }
}

Keep in mind this is just a simple example and may not result in what you expected. You can read more about the RGB colorspace here: RGB color model and here you find a RGB Color Codes Chart
