An image forming apparatus, a method, and a computer readable medium are disclosed for generating color patches for color validation of a print engine of an image forming apparatus. The method includes acquiring a validation result on a first color validation chart with a sensing device, the sensing device configured to read a color validation chart, the color validation chart having one or more color patches, and wherein the validation result compares a color accuracy of each of the one or more color patches from the first color validation chart to a target color; and determining an order of each of the color patches in a second color validation chart to be printed based on the validation result on the first color validation chart, wherein the order of the color patches in the second color validation chart is determined based on color patches that do not match the target color.
