Writing a macro in Word

I would like to write a macro so I can easily insert a red heart symbol and a red diamond symbol, but have the color immediately return to black once I've typed the symbol so I don't have to press the color button. I'm using Sierra 10.12.6 and Word 2016. Any suggestions for a non expert? I did find some instructions on one site, but they were outdated and also too complex for me to follow. Thank you!
