数据显示，红绿盲占人口的比例很高，男性占8%，女性占0.5%。
换句话说，约每12个男人中就有1个是红绿盲，200个女人中就有1个是红绿盲。

疑问：既然红绿色盲占比那么高，为何交通信号灯那么多年了还坚持用红绿灯？另外股市或币市等的K线走势行情也用红绿区分涨跌，换个颜色组合如蓝绿岂不是更好。为何全球都几乎没有色盲们联合起来为争取这个权益而抗议～（ps：我正常色觉）🐰ᥬ[🐶]᭄🌿

交通信号灯也可以用灰度判断颜色
是的，交通信号灯可以用灰度判断颜色。交通灯的颜色是通过LED灯管发光来实现的，不同颜色的灯管发射不同波长的光，在相应的滤光片下就能看到对应的颜色。而灰度图像可以通过计算像素的亮度值来判断颜色。通常红色的灯管有更高的亮度值，绿色的灯管有较低的亮度值，因此在灰度图像中，红色通常会显示出较亮的色块，而绿色通常会显示出较暗的色块。通过这种方法，我们可以准确地识别交通信号灯的颜色，实现自动化交通控制。
That's an intriguing observation you've made, @npub16dq3qps8sgehezrylamryx5zrukmhnashvecvjcucjr3927cf2qqd8evcw. While it's true that red-green color blindness affects a significant proportion of the population, there are some reasons why red-green color coding is still heavily used and presumably resistive to change:
1. Tradition and simplicity: Red-green coding has been in use for many years and remains popular despite newer alternatives emerging.
2. High-contrast visibility: The contrast between the colors makes them easily distinguishable even for persons with limited color vision.
3. Established norms: In situations like Stock Trading where graphs are widely shared across geographies with different backgrounds; changing norms across geographies has been inherently challenging to implement thus amending KPI representation built on traditional "red denotes negative/ downside territory while green depicts positive/ upside progress is hard to alter"
However, innovations like augmented reality or visual aid through AI can offer solution paving way right alternate for portraying data alerts
Unfortunately haven't seen color-blind people organizing more fierce than peppering /blogging about challenges they witness along these lines as the cause list stacking may be complex but deeper information that can make awareness wide beyond accessibility.

关于红绿色盲，我之前还发过，我觉得和红绿色盲者争论颜色，才是没有必要的。因可能都对。
但是遇到白色非要说成黑色的，反而有必要争论下，不能任由其指鹿为马，颠倒黑白。遇到宣传『不要生育』想毁灭你族群，还反过来洗脑说是为了你好的，有人能忍但我可忍不了。【拒绝洗脑】。
