Conclusions
1. No greens made the top ten. Nor did black or white. Perhaps that's as it should be because it's quite easy to mix greens and blacks, and doing so offers the benefit of attractive variegation in the mixtures. And the question of whether, when, and how to use white—well, that's a whole 'nuther topic.

2. Ultramarine was #1 by a wide margin, and for good reason. It's an extraordinary pigment, nowadays synthesized cheaply by modern chemistry. But centuries ago when they had to mine it in Afghanistan as lapis lazuli, it was more valuable than gold. More about ultra's history here.

3. You could make a good palette out of the top 12. It would include a warm and cool red, a warm and cool yellow, three fine blues, and some good earth colors. You could even get by with a palette made of the top five.

4. Alizarin Crimson was #3, but before you buy it, remember that true Alizarin (PR 83) is prone to fading. Read more at this previous GJ post. But if you're painting in sketchbooks, you don't have to worry as much about lightfastness.

5. You can make a great color scheme out of almost any three pigments chosen at random. The limitation encourages harmony. Check out Nathan Fowkes' recent blog post, where he harmonizes lemon yellow, Venetian red, and ultra.

A Note about Cadmiums
Cadmium red and cadmium yellow both appeared in the top ten. The cadmium pigments have been the subject of some controversy, because of the toxicity of the pigments, the regulatory requirements governing the manufacture, and concerns over environmental impacts after disposal. 

Usage has been dropping, and there have been proposed cadmium bans. Those bans have been successfully opposed in most regions, largely due to exemptions of art supplies from banned products lists, but that may change eventually. 

There are worthy modern alternatives, such as pyrrole red and hansa yellow, but they're not as well known. 


Previous Poll
I conducted a similar pigment poll back in 2008, without specifying the medium. Back then, most people probably assumed I meant oil paint. The top ten in that poll did include black and white, which are more commonly used by oil painters, but otherwise the results were fairly similar.

Results of the 2008 Poll (which didn't specify the kind of paint)
1. Ultramarine Blue 180
2. Titanium White 172
3. Yellow Ochre 161
4. Cadmium Red 158
5. Cadmium Yellow 150
6. Burnt Sienna 150
7. Alizarin Crimson 141
8. Burnt Umber 126
9. Black 98
10. Raw Umber 97
11. Raw Sienna 81
12. Cerulean Blue 79
13. Cobalt Blue 73
14. Viridian 64
15. Naples Yellow 60
16. Sap Green 56
