Colors that go with Deep Teal

Complementary color

≈ Mahogany#5A0500

Analogous colors

Analogous colors are neighbors on the wheel, 30° either side of the base hue. They blend smoothly and are easy to combine in backgrounds, gradients and illustrations.

≈ Spruce#005A32 ≈ Marine#00285A

Triadic colors

A triadic scheme uses three hues spaced 120° apart. It is lively yet balanced, and works best when one color leads and the other two act as accents.

≈ Plum Purple#5A0055 ≈ Green Brown#555A00

Split-complementary colors

Split-complementary keeps the base color and uses the two colors on either side of its complement (150° and 210°). The contrast is strong but gentler than a direct complement.

≈ Burgundy#5A0028 ≈ Mud Brown#5A3200

Tetradic colors

A tetradic (rectangle) scheme combines two complementary pairs at 0°, 60°, 180° and 240°. It offers variety but needs one dominant color to stay balanced.

≈ Dark Royal Blue#05005A ≈ Mahogany#5A0500 ≈ Green Brown#555A00

Monochromatic variants

Monochromatic variants keep the same hue and saturation and only change lightness, which makes them dependable for UI scales and subtle layered designs.
