What Colors Make Green?
Blue and yellow make green. It is a secondary color in the RYB (paint) color model, formed by mixing the primary colors blue and yellow.
The Answer: What Makes Green
Mixing blue + yellow produces green where the colors overlap.
Paint & Pigment Mixing (RYB)
Mix equal parts blue and yellow paint for a balanced mid-green. Shift the ratio toward yellow for a lighter, warmer green (lime); shift toward blue for a deeper, cooler green (teal). For the most vivid result, use phthalo blue + lemon yellow. Ultramarine blue + cadmium yellow produces a slightly muted, earthier green because both pigments carry hidden red undertones.
Digital Color (RGB)
In RGB additive light, green is a primary color — pure green = rgb(0, 255, 0). Standard web green is rgb(0, 128, 0) / #008000. In CMYK printing, green = 100% Cyan + 100% Yellow.
Shades of Green
Green spans a remarkable range — from pale mint green and vivid lime green to dark forest green, sage green, olive green, and hunter green. Each shade carries a distinct character and a unique paint recipe.
Color Theory: Understanding Green
Green is a secondary color in the traditional RYB (Red-Yellow-Blue) paint model. It sits exactly between blue and yellow on the color wheel, and its complementary color — the color directly opposite — is red. This is why mixing green with any amount of red produces brown or muddy tones.
In the additive RGB model used for digital screens, green is actually a primary color alongside red and blue. Full digital green is rgb(0, 255, 0). In CMYK printing, green is produced by combining Cyan and Yellow inks at full strength.
Analogous colors to green are those adjacent on the wheel: yellow-green (chartreuse/lime) and blue-green (teal/cyan). Triadic partners are red and blue. Knowing these relationships helps you build harmonious palettes that feel balanced and intentional.
Warm vs. Cool Greens
Greens span a wide temperature range. Warm greens lean toward yellow — lime, olive, chartreuse, and yellow-green. Cool greens lean toward blue — teal, sea green, hunter green, and spruce. The temperature of your base pigments matters enormously: cadmium yellow (warm, orange-biased) + ultramarine blue (cool, violet-biased) produces a slightly muted, earthy green. Lemon yellow (cool) + phthalo blue (cool) makes a bright, vivid, clean green.
Why Does My Green Look Muddy?
The most common cause of muddy green is using pigments with hidden red undertones. Ultramarine blue has a violet bias; cadmium yellow has an orange bias — both carry traces of red, green's complementary color. When these hidden reds combine, they neutralize the green and produce a brownish grey-green. Fix: choose pigments on the cooler end of their hue family (phthalo blue, lemon yellow) for the cleanest mixes. Also avoid darkening green with black — it kills vibrancy. Use dark indigo or Prussian blue to deepen value while keeping the hue alive.
Frequently Asked Questions
What two colors make green?
Blue and yellow make green. Equal parts produce a balanced mid-green. More yellow creates a lighter, lime-toned green; more blue creates a deeper, cooler green.
What colors make dark green?
Start with blue + yellow, then add a small amount of dark blue or black. Using dark indigo instead of black preserves more color vibrancy.
Blue and yellow make what color?
Blue and yellow make green when mixed together in paint.
Green and blue make what color?
Green and blue mixed together make teal or cyan, depending on proportions. More blue = deeper teal; equal parts lean toward cyan.
What colors make lime green?
Use a high ratio of yellow to blue (about 3 parts yellow to 1 part blue). Keep it vivid — avoid adding white or black, which dull the brightness.
What colors make forest green?
Mix blue and yellow to get green, then add dark blue or black to deepen it. A touch of brown adds earthy warmth for a more natural forest green.
What colors make sage green?
Mix green with grey and white to create a muted, dusty sage tone. A tiny drop of red or brown also desaturates the green for a softer look.
What colors make olive green?
Mix a yellow-dominant green with brown or raw umber. Olive is essentially a desaturated yellow-green — adding a complementary tone (red or brown) damps the brightness.
What colors make emerald green?
Emerald is a rich, jewel-toned green. Mix phthalo green with a little lemon yellow and a tiny amount of white. Avoid too much white — emerald should remain vivid and deep.
What colors make hunter green?
Hunter green is very dark and rich. Start with a forest green base (blue + yellow + dark blue) and add a small amount of brown or burnt umber for earthy depth.
What colors make army green?
Army green is a very dark, desaturated olive. Mix a yellow-green base, then add significant black and a touch of brown to reach the near-camouflage tone.
Green and red make what color?
Green and red are complementary colors — mixing them together produces brown or a muddy grey-brown, depending on the proportions and specific pigments used.
