Hi; Does anybody know of a site, tutorial or a manual that explains how to get all my colour formats and equipment synchronized? I don't have any major problems that are urgent, but I would like to go about learning how to get everything producing colours as close to the same as possible. I have googled and only found rudimentary info -- usually about printer test pages. I have printer test pages for both CUPS and hplip. Wikipedia mentions "Color is a professional color grading software application produced by Apple Inc. for their Mac OS X operating system." I would like to match the colours of the real world, my monitor, my printer, my scanner and my internet browser as closely as possible. I expect they will never be exact. I appreciate that it also depends on the configuration of applications (such as OOo, Gimp and Inkscape) being used. But I am assuming, before I make adjustments in those I should spend some time getting my equipment right first. My questions are these: * What are the basic techniques for making fairly accurate across device colour comparisons? * How to ascertain (guess) which device needs the adjustment? If I could adjust the real world, I would. * Is there a manual that explains in some depth the various colour codes that are used? I have played with colour on an ad hoc basis so I am familiar with some of the basic codes, but I suspect there is a deeper rational than I have learnt. * Are there tools and specialized test pages that can help? Remember, this not urgent. It is something I am going to work away at; but any help, tips or guidance could prevent me and others who are interested from wasting time on misguided irrelevancies. -- Regards Bill; Fedora 9, Gnome 2.22.3 Evo.2.22.3.1, Emacs 22.2.1
