You can use the SPECIAL COLOR for that.  For example:

REM Wed SPECIAL COLOR 0 0 160 This is BLUE

will produce a blue calendar entry when run via:

     rem -clc

See the source code "src/calendar.c" (specifically, the "Colorize"
function) for the algorithm Remind uses to map RGB triplets to ANSI
escape sequences.

Short version: If any of  R, G or B component is greater than 64, that
component is "on".  If any is greater than 128, then the result is considered
"bright".  The 16 combinations of "bright", "red-on", "green-on" and
"blue-on" are mapped to 16 corresponding ANSI escape sequences.
