A method for creating a duotone color effect from a lightest color and a darkest color, including: obtaining a source image in a red-green-blue (RGB) color space; obtaining a lightest color RGB tuple and a darkest color RGB tuple; generating an international color consortium (ICC) device link profile based on the lightest color RGB tuple and the darkest color RGB tuple; and converting the source image in RGB color space to a duotone image in RGB color space using a color conversion function with the ICC device link profile.
