What colours make green: clean greens, sages and forest greens

Green is yellow plus blue, but every yellow and every blue makes a different green. The cleanest greens come from a green-shade yellow and a green-shade blue with no red between them. Below are the working two-pigment greens, then how to push them lighter, deeper, cooler and earthier without going muddy.

The core yellow plus blue greens

Start with two tubes. The bias of each one decides whether you get a clean spring green or a dusty olive.

  • #A8C84A

    Spring green

    • Cadmium Yellow Light3
    • Cerulean Blue1

    Cool, fresh, slightly opaque. Reads as new leaves.

  • #3E8744

    True bright green

    • Hansa Yellow Light3
    • Phthalo Blue1

    The cleanest, highest-chroma green most palettes can hit.

  • #7A7A36

    Olive green

    • Cadmium Yellow3
    • Ultramarine Blue1

    Warm yellow plus warm blue gives a duller, golden-olive green by design.

Lighter, deeper and cooler greens

Once you have a clean base green, shift its value before you shift its hue.

  • #98A084

  • #1F4A33

    Forest green

    • Phthalo Green70%
    • Burnt Umber30%

Muted and earthy greens

For landscape and foliage, pure mixed greens often look too sweet. Knock the saturation back with a touch of the complement (a warm red or a burnt sienna) and the green starts to read like a real leaf.

  • #6F7536

    Olive earth

    • Yellow Ochre55%
    • Ultramarine Blue45%
  • #4A5226

    Moss green

    • Sap Green70%
    • Burnt Umber30%

Why mixed greens go grey or muddy

If your green looks dull when you wanted bright, the blue almost certainly carries red in it. Ultramarine, Cobalt Blue and Indanthrone all lean violet, so adding yellow drags the mix toward all three primaries. Swap to Phthalo Blue or Cerulean for cool, clean greens. If the green is still flat, you have probably added a fourth tube (often white) and dropped the chroma. Rebuild with just two pigments and tint last.

Frequently asked questions

What two colours make the cleanest green?
A green-shade yellow (Hansa Yellow Light or Cadmium Yellow Light) with a green-shade blue (Phthalo Blue or Cerulean). Both tubes lean toward green, so red never enters the mix, and red is what turns greens grey.
How do I mix green without phthalo or sap green?
Yellow plus blue still works, you just need bias-aware tubes. Cadmium Yellow Light plus Cerulean Blue gives a cool, opaque spring green. Yellow Ochre plus Ultramarine Blue gives a usable olive earth for landscape.
Why does my green go grey when I add white?
Titanium White is cool and slightly desaturating, so it pulls a mixed green toward grey-mint. Re-tint with a small dot of the original yellow to recover the chroma, or pre-mix Zinc White into the green for a gentler lift.
