Is there really a CMY color model?

Most references I can find immediately follow (or even precede) it with CMYK color model and specifically talk about printing applications (which are all CMYK). I am not sure if this page should really be here, or just point to CMYK color model. For CMYK we can point to specific instance like SWOP, is there something comparable for CMY?Maneesh (talk) 20:27, 28 June 2019 (UTC)[reply]
