Bold colors for good value for my casual watercolor painting party. The disks can be separated, making it easy to share the colors around a table. Notably, this set doesn't have purple in it. Instead, it has a lot of natural colors, so it's good for painting landscapes or the like. I'll probably get the bigger 6-layer version of this to add to my next party, since it's significantly nicer than the Crayola-type children's watercolors I have around. (the difference, for newbies like me, is that the amount of water in the pigment can change the color you get, whereas the kid's watercolors got to a certain saturation and couldn't get any deeper)
