At an early age, we're taught the basics, including numbers, letters, and colors. You may think you've got that knowledge nailed down, but a new test from the vision care experts at is designed to really test your ability to identify different hues—and it's a lot harder than it sounds.

The test measures how quickly you can recognize five matching colors and 10 mismatching colors. For example, a mismatching color would be the word blue spelled in green letters whereas a matching color would be blue spelled with blue letters. The test is based on the Stroop Effect, a phenomenon where conflicting streams of information interfere with your brain's reaction time.

After testing 2000 adults, 79 percent were able to get all five matching colors correct, while only 21 percent of respondents scored a perfect 10 out of 10 for the mismatching colors. They believe that different factors may affect your score such as age, emotional state, and how much you exercise.

Take the Stroop Test yourself and see how many matching and mismatching colors you can get right.
