    // use extra two bits to represent:
        // 00 : final 6 (or fewer) chars (if 'a' is 0x01, zero could have special meaning)

        // 10 : color

    // lookup first character in offset for quick start
        // offset is 27-entry table of bytes(?) that trims linear search to at most 21 entries ('d')

        // final chars, and advance to next test
        // if they do match, and bit 30 is clear, get next long (color) and return it
