Putty setting for different colors of text transmitted and received

I’m using Putty as a terminal emulator to control some equipment. The protocol is to send a command and receive a reply, each terminated by a CR/LF. The format of the command and reply are nearly identical. I’d like to show them in different colors, to make it clear which are which.

I found the colors settings, but there’s nothing to distinguish transmitted character colors from received character colors. Can putty not do this?
