I love Adblock. It stops Google from following me around and then selling my data to the highest bidder!
Sadly Firefox get most of their income from Google and for that reason I don't like turning it off, but I'm not allowing any spyware on my computer.

I've got old Nikon and Olympus scanners but rarely use them
nowdays or any other SCSI stuff for that matter. I used to like
SCSI but the industry dropped it for Firewire and USB. Still got
SCSI DAT drives, Jaz drives, Tape drives etc.

Most people can mix pink with paint it's just some white with a bit of red added and it will always be a shade of red and white, but RGB hasn't got any white and R and B give magenta, so to get pink you have to add R+G+B which puts it very close to white and going out of gamut. Also don't forget that equal amounts of RGB give grey.
Edit: The first page given by Tim doesn't seem to be written correctly and they refer to turquoise and pink?
Also to pink as magenta.
The second link is better and you can see from the colour wheel that pink isn't in it..... because it's a mixture of red and white which means it has all 3 RGB values not just 1 or 2 that all the colours in the wheel have. So Pink obviously can't have a wavelength. Magenta could have.
In colour printing there were two processes Additive and Subtractive. Additive used RGB filters. Subtractive used CYM filters. Subtractive was the most commonly used and was available in most enlarger colour heads.

I must admit I was wondering about that too. It looks pink to me
