Types of Colors: How to Classify, Choose and Specify a Logo Palette

In logo design, "types of colors" refers to two separate systems. The first describes how colors relate to one another: primary, secondary and tertiary hues; warm and cool colors; and neutrals. You use it to choose a palette. The second describes how a color is defined inside a file: RGB, hex, CMYK and spot colors. You use it to deliver that palette correctly to screens and printers. A usable logo palette needs both. Choose the colors by their relationships, then record each one in every color model the logo will be delivered in.

Key terms used in this guide

• Hue: the color family itself, such as red, blue or green.
• Saturation (also called chroma): how intense or muted a hue is.
• Value (or lightness): how light or dark a color is.
• Tint, shade and tone: a hue mixed with white, with black, or with gray.
• Fill and stroke: in a vector file, the color inside a closed path and the color applied to the path's outline.
• Swatch: a named, saved color definition in design software. A global swatch updates every object that uses it when you edit it once.
• Color model: the numeric system a file uses to describe a color, such as RGB or CMYK.

Color-wheel types: how colors relate

The traditional artist's color wheel uses red, yellow and blue as primary colors. Mixing two primaries produces a secondary color: orange, green or violet. Mixing a primary with a neighboring secondary produces a tertiary color, such as blue-green or red-orange. This wheel is a design tool for reasoning about harmony. It does not describe how screens or printers produce color. Screens use red, green and blue light. Process printing uses cyan, magenta, yellow and black ink.

• Warm colors: reds, oranges and yellows. They tend to read as energetic and to advance visually.
• Cool colors: blues, greens and violets. They tend to read as calm and to recede visually.
• Neutrals: black, white, grays and many muted browns or beiges. They support the brand colors and are often used for type, backgrounds and one-color versions of a mark.

Associations between colors and moods are design conventions, not fixed rules. They vary by culture, industry and context, so treat them as a starting point to test, not as proof that a color will communicate a particular message.

Palette types built from the wheel

Palette type | How it is built | Typical logo use

Monochromatic | One hue in several tints, shades or tones | Clean, restrained marks; easy to reproduce consistently

Analogous | Hues next to each other on the wheel | Harmonious, low-tension palettes; needs value contrast to stay legible

Complementary | Two hues opposite each other on the wheel | Strong contrast and emphasis; can vibrate if both colors are fully saturated and placed edge to edge

Split-complementary | One hue plus the two hues on either side of its complement | Contrast with less tension than a direct complement

Triadic | Three hues evenly spaced around the wheel | Lively, varied palettes; usually works best when one color dominates

Most logo palettes assign roles rather than giving every color equal weight. A common structure is one primary brand color, one or two supporting or accent colors, and neutrals for type and backgrounds. This is a design recommendation, not a requirement.

Color-model types: how colors are specified in files

Color model | What it is | Where it is used

RGB | Additive color made from red, green and blue light | Screens: websites, apps, video, social media

Hex | A six-character notation for an RGB color | Web and digital style guides; it is the same color as its RGB values, written differently

CMYK | Subtractive process color made from cyan, magenta, yellow and black ink | Most commercial print: brochures, packaging, business cards

Spot color | A premixed ink identified by a reference from a matching system such as Pantone | Print jobs that need a specific, consistent color, or a hue that CMYK cannot reproduce well

Grayscale and one-color | Black, white or tints of a single ink | Faxes, stamps, engraving, embroidery, single-ink print and low-cost reproduction

Conversions between these models are not one-to-one. Some bright RGB colors, especially vivid greens, blues and oranges, fall outside the range CMYK inks can print. When converted, they shift toward a duller version. A spot ink can sometimes reach a hue that CMYK cannot. Converted values are therefore starting points. Each print and screen value should be checked rather than assumed to match.

Step by step: building a logo palette you can deliver

• 1. Design the mark in black and white first. A logo that works without color will survive one-color reproduction and low-contrast backgrounds.
• 2. Choose a palette type (monochromatic, analogous, complementary, split-complementary or triadic) and assign roles: primary, accent and neutral.
• 3. Check value contrast as well as hue contrast. Two different hues with similar lightness can merge, especially for viewers with color-vision deficiencies or when printed in grayscale.
• 4. In the vector file, create a named global swatch for each brand color and apply fills and strokes only from those swatches.
• 5. Record each color in every model you will deliver: RGB and hex for digital use, CMYK for process print, and a spot reference if the brand uses one. Choose each value deliberately rather than relying on one automatic conversion.
• 6. Export separate versions as needed: full color, reversed for dark backgrounds, one-color and black, each in color modes suited to its destination.
• 7. Document the palette in a short color specification listing each color's name, role and values in each model.

How to verify the result

• Check the document color mode: an RGB document for digital artwork and a CMYK document for print artwork, unless your printer specifies otherwise.
• Confirm that every object uses a defined swatch, and remove unused or near-duplicate colors that could print as extra inks.
• For spot-color files, use a separations preview to confirm that only the intended inks appear.
• View the logo on light, dark and photographic backgrounds, and in grayscale.
• Proof print colors on the actual output method or substrate before approving them. On-screen previews cannot guarantee printed color.
• Open delivered files to confirm their contents. A file extension such as .eps, .pdf or .svg does not prove that the artwork is fully vector, uses the stated color mode, is editable, or may be reused.

Accessibility guidance in the Web Content Accessibility Guidelines exempts text that is part of a logo or brand name from contrast requirements. The exemption does not cover headings, labels or body text placed near the logo, which must still meet the applicable contrast criteria. Strong logo contrast is still a sound design recommendation.

What this guide cannot confirm

No brand-specific evidence was supplied for this article. It includes no particular color values, spot-ink references, printer specifications, ink limits or paper stocks. The principles above are general. Exact values, acceptable color variation and file requirements should come from your brand guidelines, your printer or production vendor, and the platforms where the logo will appear.
