Abstract
The problem of color image composition from original grayscale images is considered. A few models are proposed and analyzed, which are based on the observation done on many color images that in average a proportion exists between primary colors in images. Re-coloring of grayscale images are performed in the RGB color model and the Golden, Silver, Aesthetic ratios and other rules of proportions are considered between the primary colors. The gray is used as the main color to be map into the three colors at each pixel. We also describe a parameterized model with the given ratio of re-coloring images.
