Lots of dupont wires.
So many color, pin combinations.
Where is the one you need ?
This wires holder helps :
@vroemm, I don't mean to disrespect you, only to disagree with you. This is what I would recommend for holding Dupont cables:
Why ? 
They are one of the top reasons for circuits not working, both here on the forum, and with my friends at local groups. They fail so frequently, especially where the cable joins the plug. So many hours are wasted only to discover that a faulty dupont wire was the cause. I recommend avoiding them in favour of solid wire, laid flat onto the breadboard. You can easily tell when a solid wire has failed. It goes floppy! Where a component cannot be directly connected to a breadboard, usually a breadboard-compatible version of the component could have been purchased instead, if the shopper had thought for a little longer about how they would construct the prototype circuit and the final build.
@PaulRB I agree for a large part with you.
But the dupont wires have their useful moments.
And their place in a hobby room.
I will not throw them away.
Btw, breadboards are, for some cases, not exactly a perfect testing tool either.
If you throw away the dupont wires, are you then not very far away from throwing away the breadboards also ?
The wires with the square crimp housings are usually not bad. Especially if one uses terminated wires from Pololu.com and they are used in crimp housing to bundle them together to plug in to female headers or to plug on to male pins.
For example, using a 1x6 housing
https://www.pololu.com/product/1905
to hold wires for Gnd, blank, D13, D12, D11, D10 for an SPI interface, and a 2 pin housing for 5V and Gnd.
I buy 50 packs of female-female, female-male, and male-male wires in different lengths to connect things up
The wires with the round encapsulated ends can be more troublesome.

I love breadboards. I avoid using dupont wires whenever I can. As I said before, I use solid wire and try always to buy components that can be connected directly with breadboards. Like these, for example:
Using the short solid wires sure does help prevent things from getting lost in the jungle. Connections are easier to verify as well.
Just don't use your tuned antenna PaulRB. One end isn't stripped

Actually when I make wire antennas I used to push the insulator back while making the cut, so it's insulated and also will cause less injury if it pokes someone in the eye. I now also make a small loop at the end.
Once had a little wire bending jig for making breadboard jumpers of custom lengths, but it disappeared and I've not been able to find a replacement. Anyone know where I could get one? (if they still make them).
Hi,
I googled wire bending jig for making breadboard jumpers
and got this

Most of the problems I've had with the Dupont connectors are with the pin type. The female type fit snugly on pin header strips very reliably, I use them for almost everything... for proto boards I cut and strip my own solid conductor wires. It's better because you can control the length.

Well as an experienced electronics hobbiest you're being unduly harsh, I use these all the time
and they are very handy. You just have to know they are for signals only, not power.
The best pre-made breadboarding hook-up wires I've seen were too expensive, and not obtainable
any more (Maplin out of business). Making your own from 0.6mm single-core wire is my usual
technique, but the pre-made dupont crimped ribbons are often useful for bussing signals between
boards.
Hi,
What would you call DuPont Wires, I have the "round molded type" and the "inserted crimp square type" of wires and don't have much of a problem with either.
I don't expect them to be 100% reliable, so if any obvious circuit problem occurs, its the wires I suspect first.

Actually i'm agreed.
But i really mean that they are good to have anyway. But yes, dupont cables and breadboards are not wery reliable. But good for small projects i think

If I am doing a project that has some large size to it, I get a section built on protoboard, make sure it works, then transfer it to veroboard/project board and solder an assembly.
Then do another section, I put power supply LED on each section to give visual of power applied, and provide some test points.

I have no idea why Dupont wires get such a badd press.This prototype turned out OK in real life
Heh. I just remembered what day it is. Got me there for a while!
