> Can someone give be a brief rundown on how OpenBSD handles color on console?
It depends upon the terminal emulation being used. OpenBSD provides both a `sun' terminal emulation, which is the default on sparc and sparc64 (use either TERM=sun for faithful behavioul or TERM=rcons-color for the colour extensions), and a `vt220' terminal emulation, which is a subset of the VT220 command set, with some xterm control sequences recognized (use either TERM=vt220 or one of the wsvtXX matching your number of rows). The SGR (ESC [ * m) sequences recognized by the vt220 emulation are 0 (reset), 1 (bold), 4 (underline), 5 (blink), 7 (reverse video), 30-37 (select fg color), and 40-47 (select bg color) [in fact, a few VT300 sequences are also recognized but they don't matter here]. There is no support for more than 8 color code using 90-97 and 100-107. Also, keep in mind that, depending upon the actual video hardware being used, the hardware may not be able to output what the escape sequences are requesting. Not all hardware supports blinking or underline, for example.
