Some stars look slightly orange or blue, but the fireflies all look green to me. I think the red flashes are airplanes. Seriously, I know there are different species of fireflies and they use different codes of flashes, but I don't know about different colors. I'm guessing they all use the same chemistry, so the color would be easiest to stay the same, and that's why they use timing. There wouldn't be a noticeable doppler shift for light. Maybe the ones seen farther from your center of vision could appear different colors if there's a different concentration of receptors for different colors. I know not all colors can be seen equally well in peripheral vision. Red is worst.
It is a nice night for fireflies, one of several lately in our yard. --Dave Nutter On Jun 28, 2014, at 10:50 PM, Linda Orkin <[email protected]> wrote: > Does anyone else notice that some of the flashes look like different colors. > Reds and greens.
