I got these in the Sept 2022 plus box. I'm still getting the hang of them and watercolors in general. They seem pretty versatile. It's hard to tell the difference in the graphite before adding water but much easier after that. The brown is more reddish, a rusty shade, and the red is as others have noted probably meant to be burgundy but strongly purple so if you don't think of the red as a red it's less disappointing. When turned into a wash they're extremely delicate muted pastels! The white is translucent and I'm not sure how to use it other than for mixing.
(Yes I know my painting is... something else. I did it fast, without any patience, and also messed around after it dried but I'm also not claiming to be a true artist lol. The picture doesn't do an justice to the super pale washes in the petal formation at the top right corner btw. The unicorn's outline is the brown pencil which I used for the ground, the water is the blue pencil, there was some teal in the hooves and green in the grass originally, and the horn is brown and white pencil. I forgot to use the red... no wait I added some lines to the hair along with the brown.)
