Okay, you're going on a trip and can only take 10 tubes of paint.

2. I paint with acrylics also. I like your list. I'd add cadmiun yellow deep.

It's like a taxi cab yellow that covers well when needed but can also be lightened to a paler yellow.

[lunatica]

9. I would add Ultramarine blue

I like all the colors everyone listed.

[edhopper]

10. You don't need the black or the Greens

you can make black with blue and umber and mix any green you need with other colors. Adding black to a color really dulls it.
I would ad Alizarin Crimson for a more intense red and violet. Pthalo blue is also good when you need a really strong blue.

[femmedem]

11. My choices:

Titanium white
Cadmium yellow light
Vermillion
Permanent alizarin crimson
Cerulean blue
Ultramarine Blue

I could stop right there but to get to ten I'd add:
Transparent red oxide
Burnt umber
Yellow ochre
Ivory black

I understand why some people wouldn't include a black in a limited palette, but with ivory black I can use an even more limited palette: the Zorn palette, just titanium white, yellow ochre, vermillion and ivory black, with ivory black working as the blue. The ivory black and yellow ochre make a nice olive green, too.

I work in oils.
