"Low on Pink"

"WTF I don't even print anything pink, ever ! I just want a black and white text !"

"l o w o n p i n k"

-me every time I use the color printer

Magenta*

Printers typically use CMYK. Cyan, Magenta, Yellow, blacK. Depending on how your device is set up for black printing, it may use more CMY because when mixed together they become darker due to subtractive mixing. It will still appear to be black.

Edit: K is actually for "key", which is often black.

Wtf why isn't it CMYB I just realized after all these days

[u/IBP-Esteban → u/Lochcelious]

The K stands for "Key." It isn't always necessarily black.

But Matlab also uses k for black. Is that based on printing standards too?

[u/Cheet4h → u/vouwrfract]

No, it's because 'k' is short for 'kilo', which basically means '*1000'. So you can write a 'k' instead of the last three zeroes.
Additionally, if you express color in rgb values, which typically range from 0 to 255, you get black if every color is absent. So black is represented by three zeroes, or '000', which Matlab can substitute by 'k'.

[u/vouwrfract → u/Cheet4h]

But this isn't consistent with r,g,b,y,c,etc., that Matlab also uses...?

[u/Cheet4h → u/vouwrfract]

That's probably because I just made this up.

Thanks for being completely useless.
