A color blindness test checks if someone can see colors properly. It often uses pictures made of colored dots, called Ishihara plates. These plates have numbers or shapes hidden inside them. People with color blindness may not see the numbers or shapes clearly. The test helps find out what type of color blindness a person has, like trouble seeing red and green or blue and yellow. Knowing this can make it easier to handle challenges with colors in everyday life and find helpful tools or solutions.
