Changing the color output

The terminal output is colored per default but follows the value for the IAI_CALLGRIND_COLOR environment variable. If IAI_CALLGRIND_COLOR is not set, CARGO_TERM_COLOR is also tried. Accepted values are:

always, never, auto (default).

So, disabling colors can be achieved with setting IAI_CALLGRIND_COLOR or CARGO_TERM_COLOR=never.
