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 {argument name="background color palette" default="Olive Green and Mustard Yellow"} tone. At the center, the hidden number {argument name="hidden number" default="Dark Pink and Salmon Powder"} is formed by contrasting dots {argument name="hidden number" default="67"}. The surrounding area outside the main circle is filled with darker, softer green and brown dots, creating a classic medical optical illusion effect.
