1. A method for a computer system to perform printing ink consumption estimation, wherein the method comprises:
obtaining printing content associated with a document that is printable using a printer;
based on the printing content, generating an image representation of the document, wherein the image representation includes an array of multiple pixels associated with first color information from a first color space;
performing color conversion by converting (a) the first color information from the first color space to (b) second color information from a second color space associated with the printer;
estimating an amount of printing ink required for printing the document based on the second color information from the second color space; and
providing the estimated amount of printing ink to a user via a user interface.
