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.
