石原氏色盲测试图

An Ishihara color blindness test plate consisting of a large circular field filled with densely packed dots of varying sizes. The background dots within the circle are shades of {argument name="background colors" default="olive green and yellow"}. Embedded in the center is the number {argument name="hidden number" default="67"}, formed by dots in contrasting shades of {argument name="number colors" default="muted red and coral"}. The area outside the main circle is filled with darker, muted brownish-green dots, creating a seamless pointillism texture typical of medical optical illusions.
