How to choose logo colors

Updated 2026-09-14 · 3 min read · by the ColorSwoop team

Logo color is a strategic decision disguised as an aesthetic one. Here is how to make it deliberately — and how to test it before it is on a truck.

1. Design in one color first

Draw the mark in black. If it is recognizable at 16 pixels and as an embroidered patch, you have a logo. Color comes after shape.

The only three colors a mark must work in
Black on white, white on black, and a single gray for the grayscale print and the embossed version. Everything else is optional.

2. Look at the category, then do the opposite

Finance and tech default to blue; food to red and yellow; wellness to green. A palette that contrasts with the category is remembered faster. Do not fight the category if trust is the whole product — but know that you are choosing conformity.

3. Pick a primary with meaning you can defend

Each color page on ColorSwoop lists what the hue commonly signals and where it is used. Choose a primary whose associations match the brand promise, then check it against the personality words you wrote down for the brand. The marketing guide covers which associations actually hold up.

4. Test reproduction

AaThe quick brown fox
#FF3B30 on #FFFFFF 3.55:1 · AA large The logo red on white. Fine as a mark, too light for small wordmark text.

#FF3B30 on #111111 5.32:1 · AA On black, the same red passes for large text.
AaThe quick brown fox
#FCA311 on #FFFFFF 2.02:1 · Fail Amber on white: many logos live here and cannot be used as text at all.
AaThe quick brown fox
#14213D on #FCA311 7.9:1 · AAA Navy on amber: the pair that lets a two-color logo carry its own name.
Contrast on white and on black, straight from the color page. A logo color that fails on one background needs a rule for that background.

Then two tests no swatch shows you:

A red-and-green mark under the most common color blindness, and in grayscale. If the two colors carry meaning, they must also differ in lightness.
  • Print: check CMYK values; very saturated blues and oranges shift in print. Every color page lists them.
  • Small sizes: thin logos in light colors disappear on light backgrounds.

5. Build the brand palette around it

Examples

Confident tech (navy, amber accent) · warm consumer (terracotta) · premium (black and gold).
Fresh and natural: a green that reads as organic without being the category's default lime.

FAQ

How many colors should a logo have?

One or two. A single-color logo reproduces everywhere (embroidery, stamps, favicons); a second color adds personality. Save additional colors for the wider brand palette.

Should a logo work in black and white?

Yes. Design the mark in one color first, then add color. If it only works in color, the shape is not strong enough.

What logo colors do competitors use?

Check the category before choosing. If every competitor is blue, a warm color like coral or terracotta becomes an instant differentiator.
