        ' If you wish to make a color look more like another color
        ' then you could tint it. Say you have a greyscale image
        ' and want to turn it into red. You could tint it red.
        ' you take each color value and halve it. The color where you want to 
        ' tint it with you halve to. Then you add them together to form the new color.
