Aren't crossover cables "yellow"? Why use one unless required?

There are plenty of straight through yellow cables. I screen them with
my tester.

I have a bag of crossover cables.
They're any color they want to be.

I used to use them for.... I forget.
I think I used to use them either for computer to computer file transfer
before USB existed, or, maybe when I was connecting a WiFi transceiver to
my laptop RJ45 port.

I don't actually remember why we used these cables long ago.
Do you?

Some old hubs and routers wanted a crossover on the input port and you
could use them to connect a couple of machines without using a hub.
Most are yellow but there is no reason they have to be.
If you do buy a crimper, don't cheap out. The $10 ones suck. A good
one is $60-100 depending on where you buy it but it has dies for 4, 6
and 8 wire connectors. There are also 2 kinds of connector, one for
stranded wire and one for solid.
