"The Science Behind Red and Green as Eclipse Colors"

Experts recommend wearing shades of red and green during the upcoming solar eclipse to experience the unique Purkinje effect, which alters color perception during the transition to twilight vision. As our eyes switch from cone to rod cells, warmer colors appear less vibrant while greens and blues become brighter. This phenomenon, occurring 4-5 minutes before totality, creates a real-life science demonstration on clothing. However, the effect won't show up in photographs, as it's a result of how our eyes interpret light.

"Choosing the Right Colors for the April 8 Solar Eclipse"

During the partial solar eclipse on April 8, people are encouraged to wear green and red to experience the Purkinje Effect, where the eye's sensitivity to luminance shifts from red to blue in low light. This phenomenon occurs during the intermediate phase before totality, making greens appear brighter and reds darker due to the eye's response to low light conditions. Although this effect won't be visible on camera, it provides an interesting opportunity to observe the impact of twilight vision during the eclipse.
