About Color Match (Stroop Test)
Color Match is a free online Stroop test game that pits your reading brain against your color-seeing brain. Two cards appear: the top card shows a color word, and the bottom card shows a word printed in colored ink. Your job is to decide — as fast as you can — whether the meaning of the top word matches the ink color of the bottom word.
It sounds easy until you try it. Your brain reads words automatically, so when the bottom card says GREEN in red ink, the word "green" shouts louder than the red you're supposed to notice. Fighting that urge is the famous Stroop effect, and this color match game turns it into a fast, 60-second score attack with streak multipliers.
Play a round in a coffee break, chase your personal best, and see how you stack up on the global leaderboard.
How to play Color Match
- 1
Read the top card for meaning
The top card is labeled Meaning. Only what the word says counts. From level 3 onward it may be printed in a distracting color — ignore the ink up there.
- 2
Look at the bottom card's ink
The bottom card is labeled Ink color. Ignore what the word says and focus only on the color it's printed in.
- 3
Answer Yes or No
If the top word's meaning names the bottom word's ink color, press Yes (or →). If not, press No (or ←). Example: top says BLUE, bottom says RED in blue ink → Yes.
- 4
Build your multiplier
Each correct answer is worth 100 points × your multiplier. Every four correct answers in a row raise the multiplier by one, up to ×5. A wrong answer drops you back to ×1, so accuracy matters as much as speed.
- 5
Survive the ramp
As you answer correctly the level rises: more colors join the mix, the top word starts appearing in misleading ink, and a per-question timer appears and gets shorter. If the timer runs out, it counts as a wrong answer. The round ends after 60 seconds.

Color Match tips and strategy
Translate the top word into a color first
Read the top word and hold the idea of that color in mind, then glance down and check only the bottom card's ink. Doing it in that order stops the bottom word from hijacking your answer.
Blur the bottom word
Some players deliberately soften their focus on the bottom card so the letters are less readable and the color stands out. It feels odd at first but reduces interference.
Watch out for the lure
A classic trap is when the bottom word spells exactly the same word as the top card but is printed in a different ink. The words match, the colors don't — the answer is No.
Protect your streak
At ×5 each answer is worth 500 points, five times a ×1 answer. A single mistake drops you straight back to ×1, and it takes 16 correct answers in a row to climb back to ×5. Every wrong answer also locks the buttons for a moment, so slowing down slightly to stay accurate beats guessing.
Keep your fingers on the arrow keys
On a keyboard, rest your fingers on ← and → so answering is a tiny finger movement. On a phone, hold it with both hands and use your thumbs on the No and Yes buttons.
Don't look at the score mid-round
Every glance at the score or timer is time not spent on the cards. The timer bar and ticking sound in the last five seconds will tell you when time is nearly up.
What is the Stroop effect?
The Stroop effect is the delay you experience when a word's meaning conflicts with the color it's printed in. It was described by American psychologist John Ridley Stroop in 1935, building on earlier work by James McKeen Cattell, who noticed in the 1880s that people read words faster than they can name colors.
In the classic Stroop test, people name the ink colors of a list of color words. When the words and inks conflict (RED printed in blue), people are slower and make more mistakes than when they match. Reading is so practiced that it happens automatically, and your brain has to actively suppress it to report the color instead.
Versions of the Stroop task are still widely used in psychology research to study selective attention, inhibitory control and processing speed.
How scoring and levels work
- Points: 100 × your current multiplier for each correct answer.
- Multiplier: rises by one for every four correct answers in a row, capped at ×5. Any wrong answer — including running out of time on a question — resets it to ×1 and briefly locks the buttons while the correct answer is shown.
- Levels: you level up after 6, 14, 24, 36 and 50 correct answers. New levels add a fifth and sixth color, color the top word with a misleading ink, and introduce a per-question timer that shrinks from 4 seconds down to 2.
- Leaderboard: your final score after 60 seconds is posted to the global leaderboard, and your personal best is saved on your device.

Frequently asked questions
How does the Stroop test work?
You're shown color words printed in colored ink and must respond to one feature while ignoring the other. Because reading is automatic, the word's meaning interferes when it conflicts with the ink color, which slows you down. That slowdown is the Stroop effect.
What's the difference between the top and bottom cards?
For the top card, only the meaning of the word matters. For the bottom card, only the ink color matters. You answer Yes when the top word names the bottom card's ink color.
What is a good score in Color Match?
Scores depend heavily on accuracy, because the multiplier rewards long streaks. A few thousand points is a solid first round; once you can keep ×4 or ×5 streaks going through the faster levels, scores climb well into five figures.
Does the Stroop test measure anything real?
Versions of the Stroop task are widely used in psychology research to study attention and inhibitory control. This game is designed for fun and practice, though, not as a diagnostic or clinical test.
Can I get better at the Stroop effect?
Most people improve noticeably with practice as they learn strategies like reading the top word first and focusing on the ink below. The underlying interference never fully disappears, which is what keeps the game challenging.
Is Color Match color-blind friendly?
We use bright, well-separated colors on a dark card to make the inks as distinct as possible. Players with some types of color vision deficiency may still find certain pairs, such as red and green, hard to tell apart.
Is Color Match free?
Yes. Color Match is completely free, needs no download or sign-up, and works in any modern browser on phones, tablets and computers.
