An advanced color image can be obtained in a first image format comprising a number of parameters at a first bit depth per pixel. Values of the number of parameters of the advanced color image can be encoded into second values of one or more legacy containers, where each of the one or more legacy containers are of a second image format including the same number of parameters at a second bit depth per pixel. The advanced color image can be stored and/or communicated as the one or more legacy containers. ## Claims ### Claim 1 A method for storing advanced color images using legacy containers, comprising: obtaining an advanced color image in a first image format comprising a number of parameters at a first bit depth per pixel;
