<http://home.woh.rr.com/jbmatthews/a2/lores.html>I have a clear memory of the NTSC video red being a dark shade, as Linards suggests. I have no idea why the Applesoft manual calls it "magenta," which I identify with a secondary color having sRGB components (0xFF00FF). Of course, the html rendering is itself a function of the monitor's calibration.
Color 1 has only one bit of four set, so its luminance value is 25% of white. The hi-res colors (not white and black) all have two bits set, and so have a luminance value of 50%, so lo-res color 1 is definitely a "dark" shade. (Note that 0xFF00FF has a luminance of 67%--very much a "light" color. -michael AppleCrate II: An Apple II "blade server"!
