Abstract: In some embodiments, a visual content proofing system obtains visual content for proofing and a list of multiple target devices. The visual content is to be rendered by each of the multiple target devices. For each of the multiple target devices, the visual content proofing system determines a supported color region in a reference color space according to a color profile of the target device. The visual content proofing system further determines a commonly supported color region in the reference color space for these multiple target devices and a design device used for designing the visual content. By using the commonly supported color region, unsafe colors in the visual content can be determined and be replaced with safe colors to generate a revised visual content which can be rendered accurately by all of these target devices.
