Add CMYK color format

[lukebsa]

Can you add the option to use CMYK color format? Great app!

Can you elaborate? There's already CMYK support on the second tab in the app.

Or do you mean CMYK support for the text inputs. If so, what format would you expect the CMYK to be outputted and written in? For example, HSL uses the format hsl(0deg 0% 100%), but there's no convention for CMYK.

I mean CMYK support for text inputs. I would suggest percentage CMYK(0%, 89%, 76%, 11%) or decimal CMYK(0.00, 0.89, 0.76, 0.11). Perhaps this could be changed in the config.

Yeah, sounds good. CMYK( => cmyk though. I'll look into this in a month or so.

I fully support the request, and awaiting this addition to this awesome app.
Of lukebsa's suggestions for format I think percentage is preferable as it seems to me it's used more often in apps in general.
Cheers!
