Tertiary Colors in Logo Palette Design

What tertiary colors are

Tertiary colors are the hues made by mixing a primary color with a secondary color that sits next to it on the color wheel. On the traditional red-yellow-blue wheel taught in art and design, there are six of them: red-orange, yellow-orange, yellow-green, blue-green, blue-violet and red-violet. They fill the gaps between the three primaries and three secondaries, which turns a six-step wheel into a twelve-step one.

In logo work, tertiary colors matter in two ways. They widen the range of hues you can choose from when building a palette, and they are the in-between colors that give a mark a more specific character than a pure primary or secondary color usually does.

How tertiary colors relate to primary and secondary colors

Tier | How it is formed | Colors on the traditional RYB wheel

Primary | Cannot be mixed from other colors in this model | Red, yellow, blue

Secondary | Equal mix of two primaries | Orange, green, violet

Tertiary | Mix of a primary and an adjacent secondary | Red-orange, yellow-orange, yellow-green, blue-green, blue-violet, red-violet

The naming convention usually puts the primary first and the secondary second, joined by a hyphen, so it is red-orange rather than orange-red. Some designers use other names for the same hues, such as vermilion, amber, chartreuse, teal, indigo and magenta. These names are informal and do not correspond to fixed color values.

Why the answer depends on the color model

The six-name list above comes from the red-yellow-blue model, which is a teaching and painting tradition. Screens use the additive RGB model, where the primaries are red, green and blue and the secondaries are cyan, magenta and yellow. Print uses the subtractive CMYK model, where cyan, magenta and yellow are the primaries. Each model produces a different set of in-between hues, so a tertiary color in one model is not necessarily the same tertiary color in another.

Terminology also varies. Some older color-theory sources use "tertiary" for the mix of two secondary colors, which produces muted browns and olives rather than bright in-between hues. In branding, "tertiary color" is also commonly used to mean the third tier of a brand palette, such as a minor accent used after the primary and secondary brand colors, whatever its position on the wheel. When a brief or style guide mentions tertiary colors, it is worth confirming which meaning is intended.

Using tertiary colors to build a logo palette

Standard color-wheel harmonies work with tertiary colors in the same way as they do with primaries and secondaries. These relationships are a starting point for choosing hues. They do not decide value, saturation or contrast, which still need separate checks.

• Complementary: pair a tertiary with the hue directly opposite it, such as red-orange with blue-green, or yellow-orange with blue-violet. This gives strong hue contrast for a mark and its background or a symbol and its wordmark.
• Triadic: use three tertiaries evenly spaced around the wheel, such as red-orange, yellow-green and blue-violet, or yellow-orange, blue-green and red-violet. This gives variety without repeating a primary-color look.
• Analogous: group neighboring hues, such as yellow-green, green and blue-green. This produces a calmer, unified palette that relies on value differences for legibility.
• Split-complementary: pair a hue with the two neighbors of its complement, such as orange with blue-green and blue-violet. This softens a direct complementary clash.

Hue choice alone does not guarantee readability. Two tertiaries can be well apart on the wheel and still have similar lightness, which makes them hard to tell apart in grayscale, for viewers with color-vision deficiencies, or when the logo sits small next to text. Checking the palette in grayscale and testing contrast between foreground and background colors catches this early. Where logo colors also carry text on screen, the contrast ratios in the Web Content Accessibility Guidelines are a common benchmark.

Specifying tertiary colors in vector logo files

Because there is no single standard value for a hue such as blue-green, a logo palette needs explicit color definitions rather than names. Deliverables usually record each color in the formats its uses require: HEX or RGB values for screen, CMYK breakdowns for process print, and a spot-color reference where a printer needs exact matching. This material contains no specific values, so any numbers should come from the actual artwork or the brand's style guide.

• Define palette colors as global or named swatches in the vector file, so a change to one swatch updates every object that uses it.
• Keep separate, labeled color versions for screen and print instead of relying on automatic conversion at export.
• Check saturated tertiaries for out-of-gamut warnings when converting from RGB to CMYK. Vivid blue-greens and bright oranges are common candidates for visible shifts in print.
• Supply one-color, black, white and reversed versions so the mark still works when the tertiary palette cannot be reproduced.
• Record the palette and its intended uses in the style guide, including which color is primary, secondary or accent in the brand sense, so the two meanings of "tertiary" are not confused.

An SVG, AI, EPS or PDF extension does not prove that the colors sit on editable vector paths. A file can wrap an embedded raster image, or contain a raster preview, in which case colors are baked into pixels and cannot be changed swatch by swatch. Opening the file in a vector editor and confirming that shapes are selectable paths with assigned fills is the reliable check before recoloring or extracting a palette.

Recoloring an existing logo

Being able to download a logo file does not grant permission to change its colors or use it in new work. Brand owners usually control approved palettes and color variants through trademark rights and usage guidelines, and the fonts in a wordmark may have their own license terms. Exploring tertiary-color alternatives for a logo you do not own or represent is best limited to private study unless the owner has approved the change.

What this overview does not cover

This article covers the general color-theory definition and its practical use in vector logo palettes. It gives no specific color values, conversion figures or print-matching references, because no measured or documented palette data was provided. Exact behavior of color conversion and gamut warnings depends on the design application, its version and the color profiles in use, so check those against the relevant software documentation and printer requirements.
