Green. Peak visual acuity is 555 nm . . . which is green.

And someone needs to explain "please and thanks" to me which I never ever heard anyone say until the past couple of years.

Maybe that's the weakness with green. It's right in the center of our color spectrum and can easily be blended in and confused with other things. Perhaps there's better contrast with red because it's off to one extreme.

OK. I get that is the meaning. I just don't know when that became an abbreviated way to say it. The couple of friends I know who seem to use it the most are both from the upper midwest: Michigan upper peninsula and Wisconsin. I wonder it it's a regional thing.

There are definite mental/emotional asssocations with the color red, and that might be part of it, too. Red is a color which we associate with danger and with love. Our appetites are also triggered by the colors red and to a lesser extent yellow, which is why pretty much every restaurant chain uses one or both colors in their signs/logos (McDonalds, Burger King, Carl's Jr., Wendy's, Jack in the Box, Pizza Hut, Papa John's, Dominos, KFC, Chick-Fil-A, Dairy Queen, In-N-Out Burger, Five Guys, Hardee's, Arbys, Chipotle, Tim Hortons (for those of you of the Canuck persuasion) . . . Taco Bell and Subway seem to be rare exceptions (but even Subway does use yellow)).

I think green might actually help us distinguish more detail, like in night vision goggles. But then red light strains the eyes less and is less detrimental to our own night vision, like on a submarine or on headlamps. Maybe that's the tradeoff?

Needed to glove that. Terrible rebound. Devils dead. Blues happy.

Schmid was terrible. And . . . they finally pulled him for Vanacek.

They're just resting him. They didn't pull him thinking the other goalie would make a difference for this game.

The last goal was with a two man advantage since they had pulled the goalie. I wasn't concerned about giving up a goal down two men.

There's a difference between visual acuity and sensitivity.

We have the highest sensitivity right in the middle of the green spectrum, but a lot of folks find that they have difficulty focusing on bright green reticles, as sharply as a red reticle.
