In: Other Share Facebook 3 Answers Voted Frobbelito Added an answer on June 18, 2019 at 11:22 am The CMYK (Cyan, Magenta, Yellow, Key (black)) model works by partially or entirely masking colors on a lighter, usually white, background. The ink reduces the light that would otherwise be reflected. Such a model is called subtractive because inks “subtract” the colors red, green and blue from white light. White light minus red leaves cyan, white light minus green leaves magenta, and white light minus blue leaves yellow. There are printing methods where more colors are added, such as green and orange. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Luckbot Added an answer on June 18, 2019 at 8:09 am Cyan, Magenta and Yellow are the negative colour bases. When you mix ink, you will get the negative sum of both colours (mixing all colours perfectly will result in black) because more light colours are absorbed. Red, Green and Blue are the positive colour bases and need to be used when the positive sum is needed, like when mixing light (mixing all will result in white) These are anticolour pairs. When you invert colours Red will turn Cyan, Green will turn Magenta (you have propably seen an inverted colour picture) 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Rhynchelma Added an answer on June 18, 2019 at 8:35 am [Here’s some older threads.](https://www.reddit.com/r/explainlikeimfive/search/?q=magenta%20%20cyan%20red%20blue&restrict_sr=1&sort=new) 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Attachment Select file Browse Featured image Select file Browse What is the capital of UK?
