Ishihara Color Blindness Test Revealed

A Ishihara color blindness test chart consists of a large circular area filled with dense dots of varying sizes. The background dots inside the circle use the Olive Green and Mustard Yellow tone. At the center, the hidden number Dark Pink and Salmon Powder is formed by contrasting dots 67. The surrounding area outside the main circle is filled with darker, softer green and brown dots, creating a classic medical optical illusion effect.
