Over the years, I've tried different mechanisms for applying colors until
I got my hands on f-stings; then I created a tiny module with all the
colors (cR, cG, etc) which made my life so much simpler (attached). The
module includes background colors (bX); but I very rarely use those.

Then, I just use the module like this:

# place the module in a directory where your script is
# e.g., $ mkdir mymods (rename as desired)
from mymods.colors import *
# or just include the contents inline

# this simply switches from one color to the next
print( f"{cR}red, {cB}blue, {cG}green {cO}are colors." )

# color just the response
ans = input( f"Answer?: {cG}" ) # turn off color on next line
print( f"{cO}You entered: {cY}{ans}{cO}" )
# ^^^^

# to turn off each color (white commas), change the above to:
print( f"{cR}red{cO}, {cB}blue{cO}, {cG}green {cO}are colors." )

On Windows, you'll need to add this *before* using the colors:
import os
if os.name == 'nt': # Only if we are running on Windows
from ctypes import windll
w = windll.kernel32
# enable ANSI VT100 colors on Windows.
w.SetConsoleMode(w.GetStdHandle(-11), 7)

HTH,
Pierre
