So how did people manage in the days of black and white television?

From the BBC:

Sean Hargrave is a self-declared football obsessive, but when he sat down to watch the opening match of the 2018 World Cup he couldn't tell one team from the other.

He wasn't the only one struggling. Roars of frustration jumped from sitting rooms to social media as fans worldwide branded Russia v Saudi Arabia "a disgrace".

The problem? Sean, like 1 in 12 men and 1 in 200 women, is colour-blind...

Microsoft Office and Walker's Crisps

We all know that Walker's got it the wrong way round by making salt and vinegar crisps green and cheese and onion blue. We will have to live with that, even though half of use will never get used to it (I did a Fun Online Poll on this six years ago which is no longer accessible).

Microsoft used to use the same colours:
Excel = salt and vinegar = green.
Word = cheese and onion = blue
Powerpoint = ready salted = red
Outlook = roast chicken = yellow.

One of the millions of really shit things about Windows 10 is that they kept the colours for Excel and Word, but Outlook is now blue and white and Powerpoint is a sickly orange-red colour.
