You know, there was a time when the phrase 'Navy Pilot' had absolutely nothing to do with those goldurned flyering machines.

I learned that not only am I just night-blind, which I already knew, but that stars are different colors to the naked eye. They all look white to me.

They're still mostly white to the naked eye. The only heavenly bodies I can think off of the top of my head that are very obviously colorful to the naked eye are all planets.

Yeah, I can actually, seriously tell the difference between slight variations of colors and the stars look pretty much white to me, too.

An astronomer will tell you stars come in every colour they do in Master of Orion II, but to the naked eye they're pretty much white.

Maddox's image fails there because he saved it as a 256 colour GIF.

And it has more than 256? Because I count about 4.

I can tell the variation in the colors of stars but it's not nearly as interesting as it sounds. Having near-perfect night vision is fun, though.

Rather than being condescending without actually explaining anything, I'll explain anything.

Saving the image in a 256-color format will cause you to lose color information. You don't pick which 256 colors go into the image; you get a small set predetermined by the format, and colors will be changed to approximate one of the 256 colors. Therefore, if the colors he's got in the image were ever so closely related but ever so subtly different, they wouldn't be anymore after conversion to a 256-color format. They are now the same color.

Well, Maddox is indeed full of shit; however, I looked at that 256-color GIF in Photoshop CS4 and those two shades of red are in fact correctly labeled.

Oh, also: the latest Non-Adventure of Wonderella has taught me something magical.

Low-grade 256 colour .gifs are basically a legacy of the old SLOW INTERNETS ARE SLOW days. Any file saved in that format is 'optimized for web display', meaning whatever colours are found in your orginal image are converted to their closest analog on that narrow 256 colour spectrum. The gag is that regardless of whatever colour differences may have existed originally in that image, Maddox's choice to save them as a low-grade file has eliminated any such distinction.

I HAVE NOW EXPLAINED THE JOKE, EFFECTIVELY KILLING IT.

SIR, WE HAD TO BOMB THE VILLAGE TO SAVE IT.
