Iconic brands come with an iconic brand color. A color we will never forget. Well, that’s the intention of the designer, of the company. But how good is your color memory? Can you accurately recall that iconic brand color? Let’s do a short test to find out…

CONTENTS: Short-term memory | Brand color memory | The setup | Why is this important? 

About a year ago, I published an article about our color memory, which has been the most read article for a long time. It reports on a study by researchers from the Johns Hopkins University in 2015. In this blog post, I would like to do a small, similar test to check our color memory. Will you participate? Please???  

Test #1: short-term memory
In this first test, we will test your memory for a specific red. First, it will be shown to you, a bit later, you will be asked to pick that color from a few samples. The highest color difference between the reference and the other colors is delta E 1976 = 9,00; delta E 2000 = 3,75.

The colors are all within the sRGB color space, so if you have a decent, recent monitor, it should work. Please note: we are comparing colors on the same monitor, so calibration is less of an issue with this test. It is a relative comparison. But make sure there isn’t any light falling on the screen, e.g., from a window. That might hinder the test. And make sure the screen is at the maximum brightness level. 

Please click on the slides to advance. In total there are 13 slides, after the last slide, you’re back at the first slide.


Test #2: brand color memory
The second test is more challenging: it checks your long-term color memory. The test is to identify the real brand color of an iconic brand: Coca-Cola. You will see six variations of red. All of them are very specific brand colors, from the following companies: Adobe, Coca-Cola, KitKat, Netflix, Target and Vodafone. Most of them are known worldwide, the reason for picking them.

The color differences, compared to the Coca-Cola red, go up to dE76 = 21,11 and dE00 = 9,18.

For this test, calibration is more important than in the previous test: you want to see the exact color red. This is not a relative test, it is an absolute test. As with the previous test: the colors are within the sRGB color space, so a – calibrated – sRGB monitor should be sufficient.

What do you think? Which one is the real Coca-Cola red? Again: click on the slide to advance.


If you want to know the answer, please fill in the form below. The answer will be e-mailed to you right away! The e-mail address and other info won’t be used for any other purpose. The extra questions are for analysis purposes only, to see if there are differences in the different groups. As soon as I’ve received sufficient answers, I will include a statistic with chosen colors and update it on a regular basis.

Which image has the correct Coca-Cola red? (required)
123456I have no clue

Did you use a calibrated screen?(required)

Are you involved with printing in your professional life? (required)

Your genetic gender (required)
XX (female)Xy (male)I do not wish to provide this info

Your age (required)


The setup: sequence vs adjacent colors
As you probably have noticed, I’m showing the colors in a sequence, not next to each other. And that makes a difference. We are very good at seeing color differences when two colors are placed next to each other, or even on top of each other (the general practice in ‘press proofs’). But when trying to remember the exact color from our memory, it becomes much more difficult. Even when the colors are shown with only a few seconds apart, making use of our short-term memory.

If you ever want to replicate this test, e.g. with a different color or maybe even in print, make sure that there is a short pauze between showing the different colors.  

Why is this important?
For some brand owners, marketers, getting the brand color within the tiniest tolerances, is kind of religion. But does that matter? If my feeling is right, if other studies that I’ve seen are right, our color memory isn’t that good at exactly remembering a brand color. Yes, we will remember that it’s a vibrant red. But which vibrant red? That’s another story. I guess you could easily swap Coca-Cola red with Adobe red, without anyone noticing, or anyone bothering… Except for the brand owner, maybe.

PS: don’t forget to share this test!

(and another PS: there is something wrong with the counter below… for some reason the counter on this page – and this page only – doesn’t work properly)
