제2색각

초록 감지 원뿔세포의 부재로 인한 적녹 색각 이상의 일종으로, 빨강과 초록 색상의 구별이 어려움.

Deuteranopia is the most common form of color vision deficiency, affecting approximately 1% of males. People with deuteranopia lack M-cone (medium wavelength, green-sensitive) photoreceptors, causing green to appear beige or muted and red to appear brownish. The milder form, deuteranomaly (reduced green sensitivity rather than absence), affects about 5% of males. To design for deuteranopia, avoid using red and green as the only differentiating colors in charts, status indicators, or interactive elements. Blue-orange combinations remain distinguishable for most people with this condition.
