@davidrevoy TRUE! We need CMYK support because I'd switch away from Canva if Inkscape truly supported it. Please @inkscape ❤️❤️❤️ (we love u)

@davidrevoy Thanks for the coverage :ablobhearteyes: as a docs contributor myself it's incredibly satisfying to see all the work land into place.

@davidrevoy I know you're a geek + artist but as a physicist I didn't quite grok what is all the fuss about color representation and reproduction in tech. Our light sensing cells have three non-flat spectral responses, our electronic devices have non-linear outputs and finally our brain fucks up us all, processing this with cues from ambiant lightning when doing subtractive color synthesis. All this can be overcome with sane maths, good engineering and collaboration between vendors.🤔

@duckyfella Think of CMYK like a special language for printers. Artists need it to ensure their designs look great on paper, not just on screens. And it's not just about art - CMYK is used in millions of printed objects we use daily, from packaging to billboards. It's a crucial part of our visual world!

@davidrevoy Thank you!! Is it not possible to convert RGB -> CMYK though?

@duckyfella Unfortunately, it's not. A human (artist decision) has to be done. For example, you can obtain a Black by overlaying Cyan+Magenta+Yellow. But they don't overlap perfectly because you print in pass. So the industry came up with a Black ink cartridge, this one is economic too (better than three pass of CMY). But you can also do "rich black" by mixing Black ink and Cyan at 60% and manage this way many 'mix'. Color on screen doesn't work the same way.

@mond Same, this workaround exists since around 2010 and the best documentation about it is on the Fedora wiki, imo ( https://fedoraproject.org/wiki/How_to_set_CMYK_color_on_a_design_for_printing#Introduction ) But what a tedious process! If a client does a design/tracing decision after the CMYK export in Scribus, it's a ton of work to redo all the export pipeline. Oh yes, so annoying indeed.

@duckyfella @davidrevoy I'm no expert but if I know something I'm working on needs to be printed at a professional printer - then starting the workflow in CMYK means I am more likely to use colours that can actually be printed.Good software will only show you the available colours and not let you pick those that can't be printed via a CMYK process.the attached colour wheels are from Affinity Designer, one with an RGB document, the other CMYK

@rzeta0 @duckyfella Just a note about Hue(ring)Saturation/Value(triangle) color selectors: while they are familiar to the user for color picking, they are not the best option for CMYK color picking. But many software suggest this kind of view for convenience. The best way to work with CMYK colors is with sliders and percentages. E.g. with the Krita specific color docker, here doing a "pure CMY" color, without black ink dots in it (something a triangle with auto conversion cannot guarantee).

@davidrevoy is the difference between digital and print that in digital, you can add as many colors as you like and it won't get black, but IRL, the more colors you mix, that darker it gets? Simply because of physics, you're adding more material and layering it which means less light gets through.I don't know why Cyan Magenta and Yellow were chosen. My guess is that it they were more available and all necessary colors could be made from mixing them. My other hunch is that IRL, you can mix them more without getting as dark as RGB. But that's a buess.

@atro_city @duckyfella Hey, if you are curious about it, look at https://en.wikipedia.org/wiki/Subtractive_color , worth a read and you'll have all info about it.

@davidrevoy Thanks for this! I actually did a remarkably tedious course on colour theory, in Uni, which failed to clearly explain this. After reading your blog, and the replies here, I much better understand the ramifications of RGB vs CMYK colour systems.
