I've wanted a ColorChecker as a nice-to-have for a while, but real ones are kind of expensive (understandably so) for me.
As it turns out, paint samples that you can get at the hardware store for free are made with remarkably accurate colors. Although there are many like it, I found this nice video[1] about how to DIY a color checker. He lists the names of the colors in the description. But at least he confirms that even a near match works well!
However, I found that the paint companies change their colors slightly pretty frequently. But the Wikipedia article on ColorChecker[2] has a listing of the exact colors in the ColorChecker. So you can use a site like Match My Paint Color[3] to find the nearest paint color to put together a list of color names that you can then go scoop up at your local hardware store!
I didn't learn much from reading this article. Questions linger in my mind, for example: What are the CIE XYZ coordinates of each colored square? What is the spectral distribution of each square? How were the colors chosen?

The Wikipedia article is far more informative, though I'm uncertain if read the full dpreview article due to ad-induced nausea.
> What are the CIE XYZ coordinates of each colored square?
In the most expensive versions, they measure each individual patch, in case printing imperfections make the colours slightly different. And of course because you can’t get the exact same inks when a product is 50 years old!
> How were the colors chosen?
Skin and foliage; primary colours; greyscale; and miscellaneous.
They also make a 140 colour patch version - the “ColorChecker Digital SG” - that provides more coverage; 14 different skin tones instead of 2 for example!

You sound like you actually want to just generate them yourself using ArgyllCMS `targen` and `printtarg`.

I don't know about him but yes yes I do and you should want to, too! :^)

Pleasantly surprised to see dpreview still running, I thought they had shut down. It was a fantastic site back in the day. Not sure how it fares these days.

These are great, even for manually-adjusted color workflows.
Fun fact, though: You have to replace them every couple of years (or sooner) because no pigment/dye is stable, especially if exposed to bright light.
Having a test shot with one of these in it saves you untold amounts of pain later.

Many of them, especially the smaller hard-case versions, have a space to write date of first-use.

Nostalgia! I don't remember them coming out, but I was involved in setting up Calibrite. I was more involved in the monitor calibrators (my team developed the new software) and the infrastructure.
