Um... don't use color :-)

Create a list of #define's which define the length of
each ansi color string (if you need to, write a small
program to figure out lengths), then when you malloc it,
add the appropriate length to the amount allocated.
I don't remember off the top of my head how the allocation
is done - if it's through a macro, just add an extra
argument to the macro and add it the space being allocated.
Ditto for a function.  If you are just mallocing on the
spot, so to speak, then it is even easier, since you
wouldn't need to change any macro calls :)
