Seeing the World Differently: Color Blindness, Personal Stories, and Video‑Streaming Solutions

In the world of Cheng Guang, sunsets are usually described as "pale yellow" or "off‑white" rather than the vivid reds most people imagine. He cannot understand why others use bright reds and oranges to depict twilight.

As a child in the countryside, Cheng was asked to pick red strawberries but saw only a muted pink‑gray hue, leading to frustration and tears. Later, a school exam marked entirely in red ink caused him embarrassment. Only after a middle‑school health check revealed a significant color‑weakness did he realize his perception differed from the majority.

Another interviewee, Ren Tai, also experiences a similar visual world. He describes a rainy, green‑tinted meadow as "deep ink‑colored tide" and relies on shapes and outlines rather than colors. He notes that about 8% of the global male population and 0.5% of females have some form of color blindness or weakness.

Medical professionals explain that color weakness is a common X‑linked condition caused by retinal cell variations, affecting the ability to distinguish certain hues while retaining most color perception.

Technological interventions are emerging. The EnChroma glasses, launched in 2015, claim to improve color discrimination for color‑vision‑deficient users. Training programs at Beijing Tongren Hospital have shown limited success in enhancing sensitivity for mildly affected individuals.

Software solutions are also being developed. Microsoft engineer Overton and his team created "Color Binoculars," a tool that helps users with red‑green or blue‑yellow deficiencies differentiate colors. Major games such as League of Legends, Honor of Kings, and Overwatch have introduced color‑blind modes to make gameplay more accessible.

Video‑streaming platforms like Youku, Tencent Video, and iQIYI have implemented color‑weak modes. Engineer Zhang Zihao’s team built a large‑scale algorithm that remaps colors into channels perceivable by color‑weak viewers, effectively translating red tones into distinguishable alternatives.

These modes have been well received: after a month of deployment on Youku, 49% of users of the color‑weak mode were red‑weak, 29% blue‑yellow weak, and 22% green weak. Over half of the users keep the mode enabled for all content, especially favoring colorful anime and dramas.

Interviews with users such as Tony (a red‑green blind filmmaker) and Guo Lan (a jewelry professional with red‑green weakness) illustrate daily challenges in describing colors, navigating social situations, and pursuing careers that rely on accurate color perception.

The article emphasizes the importance of respecting minority groups, improving accessibility, and the role of engineers in creating empathetic, inclusive products that bridge the gap between normal and color‑weak visual worlds.
