I think you've done those b&w's with a colour splash really well. I've tried to do that and have never been satisfied with the results, but these turned out really well.
And yes, it really is always the right time to do what is right, even if it isn't easy. It's a nice sentiment that hopefully can be spread.
Don’t worry I have tried color splash or selective colors many times and not been happy with the result
Doing right is often not easy but afterwards it feels good
