20-round color focus test
What this challenge measures
This challenge uses conflicting color words and display colors. Your task is to choose the displayed ink color—not the word itself—across 20 rounds.
Scores are recreational and can vary by device, browser, display, input hardware, and environment. They are not diagnostic assessments.

How to use this color focus test
The Color Focus Test uses conflicting color words and ink colors to create an interference-style attention challenge. Your job is to respond to the ink color rather than automatically reading the word.
Accuracy is essential because the test is meant to combine selective attention with response speed. Run it in a similar browser window and minimize interruptions if you want a more consistent personal comparison.
How the score works
Lower completion time is better, but a personal best requires the mode's accuracy threshold. Harder settings use more rounds and a higher proportion of conflicting word/color combinations.
Questions about this challenge
Is this a Stroop test?
It is a recreational browser challenge inspired by color-word interference tasks, but it is not a standardized clinical or research administration of the Stroop test.
Why do conflicting words slow responses?
The task asks you to prioritize ink color while ignoring the written color word, creating an extra selection step when the two disagree.
How is a personal best determined?
The run must meet the required accuracy level, then the fastest qualifying completion time is stored for that difficulty.
