I want to say that a third of it is too light, a third too dark, and I would spend all my time mixing in the middle. Might be better if it looked more like:
Great Idea, I did something similar but not as neat. It does help beginners and is a good way to learn how to distinguish values and also provides a shortcut. As far as that Rotgut school is concerned I think our "students" are way ahead (except me) and I don't care for very many of the "ARTISTS" they chose to review. I am pretty well convinced our forum members provide plenty of information and inspiration not to mention the Artists THEY choose and share to review and draw inspiration from.
@BOB73 Yeah. But this won't beat the individual judgement of the relationship between values and chroma. Slight change in chroma with same value makes a world of difference. Everything is not black and white in heaven and arts! He He
That's what I was trying to do too. After the gray scale, I tried to get red, blue and yellow each in the same value as the middle four or five of the gray scale values. Blue was fairly easy but yellow was nearly impossible. I had a little spot in the garage to experiment when I stained my canvases and pallets but it got too hot and the daughters bought bicycles so I didn't spend as much time on it as I would have liked.
I’ve used a gray scale card one side has a hole punched in each strip if you want to lay it on a spot of a photo. I’m doing still life’s for now so I haven’t used that side but I haves used it to check steps for color mixing.

This app has a moveable value scale for your grey scaled colour photographs.
A recent upgrade identifies pigments in the W&N oil colour range.
