... which might be really confusing to someone who learned elementary arithmetic using Cuisenaire Rods. (http://teachertech.rice.edu/Participants/silha/Lessons/cuisen2.html)

    No, no, no. This being a tech-geek forum, you should all know the *real* color/number correspondance:

    0black
    1blue
    2green
    3cyan
    4red
    5magenta
    6brown/orange (dark yellow)
    7light grey
    8dark grey
    9bright blue
    10bright green
    11bright cyan
    12bright red
    13bright magenta
    14bright yellow
    15white

    "In adjectives, with the addition of inflectional endings, a changeable long vowel (Qamets or Tsere) in an open, propretonic syllable will reduce to Vocal Shewa. This type of change occurs when the open, pretonic syllable of the masculine singular adjective becomes propretonic with the addition of inflectional endings."  — Pratico & Van Pelt, BBHG, p68

      That's only one of them, the default palette used by VGA cards. But there's another one, the one used by vt100 terminals and internally by linux. That one has the red and blue bits swapped, like 0=black, 1=red, 2=green, 3=yellow, 4=blue etc. I know this because this second scheme is used by the \e]P palette changer escape sequence. (This is btw another proof why this is not the real color/number correspondence: that's only the deafult palette, you can change it to whatever you like. I've rebound magenta to orange once to display Rubik's cube patterns nicely.) The translation table between the rgb and bgr scheme is color_table in /linux/drivers/char/console.c.

      Update: see also Re: What is the Perl Color?.

        VGA cards use it as the default for backward compatibility. It was introduced by CGA cards, and on those it was not merely the default and could not be changed; it was hardwired. (CGA cards did not have any way to display a color given arbitrary red/green/blue values. They *only* had the sixteen colors, ever, period. As an added bonus, you could only get more than four of them on the screen at once in text mode (although there were tricks available to make text mode appear to be a low-res graphics mode).)

        I was pretty sure the CGA colors also match the ANSI colors, but I shouldn't be surprised that the VT100 used a different scheme; DEC did a lot of things differently from the rest of the world, such as using Category 4 (not 3, not 5) cable and MMJ connectors for networking, or the extraordinarily wacky way VMS expresses directory paths.

      Surely black, brown, red, orange, yellow, green, blue, violet, grey, white?

      Or have I read one RS catalogue too many?

        You really don't want to know the mnemonic my high school physics teacher gave us to remember the color codes on resistors.

    Good grief, and I thought *I* was the only one who learned counting with those. They go back to Kindergarten, 1963-64 at Elmwood Elementary in Rosemere, QC. I remember the ones (white) and twos (red), but that's about it.

    I also remember making a plasticene snake several tables long with a bunch of laughing classmates, but .. that's not important right now.

    Strangely, I remember that we had similar rods in elementary school, but I think the color scheme was different. I'm sure 1 was white, but one of the shorter ones (2 or maybe 3) was light blue. Also, there were a few longer rods, I think 12 and 20 long ones.
