More About Color: Why Isn't The Sky Purple?

This month, we've stumbled upon a fascinating video that answers a question you might never have thought to ask: "Why Isn't the Sky Purple?"


This video dives into the fascinating world of colors and chromaticity, exploring the underlying physics that dictate the colors we perceive in our everyday lives. Though the production isn't our own, we couldn't resist sharing this fun video.


Why does the sky prefer shades of blue over a royal hue of purple? How do our eyes perceive different color spaces? And is the sky really just electromagnetic gravy? These are just a few of the fun and interesting questions tackled in this illuminating video.
