Know Your Karl The Fog Colors
Apparently I am not the first person to think of this (via Gilly Youner):
I stumbled onto this 18th century instrument designed to measure the blueness of the sky called a Cyanometer. The simple device was invented in 1789 by Swiss physicist Horace-Bénédict de Saussure and German naturalist Alexander von Humboldt who used the circular array of 53 shaded sections in experiments above the skies over Geneva, Chamonix and Mont Blanc. The Cyanometer helped lead to a successful conclusion that the blueness of the sky is a measure of transparency caused by the amount of water vapor in the atmosphere.
I have helpfully labeled this 225 year old chart to reflect San Franciscan values:
On a serious note, this article on a blind man using the VoiceOver feature of the Color ID app is pretty amazing.
The next day, I went outside. I looked at the sky. I heard colors such as “Horizon,” “Outer Space,” and many shades of blue and gray. I used color cues to find my pumpkin plants, by looking for the green among the brown and stone. I spent ten minutes looking at my pumpkin plants, with their leaves of green and lemon-ginger. I then roamed my yard, and saw a blue flower. I then found the brown shed, and returned to the gray house. My mind felt blown. I watched the sun set, listening to the colors change as the sky darkened. The next night, I had a conversation with Mom about how the sky looked bluer tonight. Since I can see some light and color, I think hearing the color names can help nudge my perception, and enhance my visual experience. Amazing!
