Acrylic Painting Palette: Red
Get a tube of cadmium red medium (you also get a cadmium red light and dark). Cadmium red medium is a yellowish, warm red and relatively opaque.
Acrylic Painting Palette: Blue
Phthalo blue is an intense, extremely versatile blue. It goes very dark when combined with burnt umber and, because of its high tinting strength, only a little need be mixed with white to create a lighter blues. (Also called phthalocyanine blue, monestial blue, and thalo blue.)
Acrylic Painting Palette: Yellow
Start with a tube of cadmium yellow medium. You can easily create a lighter yellow by adding white to this, though if you find you’re doing this regularly, consider buying a tube of cadmium yellow light too. Remember that if you want to darken yellow to try adding its complementary color, purple, rather than black, which tends to produce an olive green rather than deeper yellow.
Acrylic Painting Palette: White
Titanium white is an opaque, bright white with a strong tinting power (meaning a little goes a long way). Some manufacturers also sell a "mixing white", which is usually the cheapest and, as the name suggests, formulated to blend well with other colors.
Acrylic Painting Palette: Black
Mars black is a relatively opaque color and should be added to other colors in small quantities until you’ve got used its strength. Another option is ivory black, but only if you’re not squeamish about it being made from charred bones (it was originally created from ivory).
Acrylic Painting Palette: Brown
Burnt umber is a warm chocolate brown that’s extremely versatile and likely to provide itself indispensable. It’s great for darkening the tone of other colors. Raw umber is very similar, but slightly lighter and cooler.
Acrylic Painting Palette: Green
Greens can be hard to mix consistently unless you’re meticulous to note the colors and proportions you used. Phthalo green is a bright bluish green. Mix it with cadmium yellow medium to get a variety of shades of greens.
Acrylic Painting Palette: Orange
Yes, you can make an orange by mixing yellow and red, but if you’re mixing an orange often, you’ll save yourself time having it ready-made in a tube, so buy a tube of cadmium orange.
Acrylic Painting Palette: Purple
It’s worth buying a very dark purple as you can waste a lot of paint trying to mix one.
