AI Thread Summary
The discussion centers on the observation of a blue rim around white streetlights, particularly the newer, brighter models. Participants note that this phenomenon may be due to chromatic aberration, where different wavelengths of light are refracted at varying angles. The blue light, being of shorter wavelength, appears more intense and distinct against the white light. This optical effect is more noticeable from a distance and may not be as apparent with older streetlight designs. Understanding the science behind light wavelengths and human perception can help explain this visual occurrence.

I hope I can describe this clearly... but its hard to see this on anything but the newer, brighter, white streetlight... and from a distance at that... but it's there, a distinct rim of blue crests and troughs. I understand that blue light is the most "intense" of the visible spectrum with its relatively short wavelength, sadly that is all the relevant information i know.

but when i stare into a white streetlight, I can't seem to figure out how this light pattern arises. It does not seem gradual, it looks more like a thin, jagged blue rim surrounding a white sphere in my vision.
