You could probably embed raw ANSI SGR color escape sequences { maybe from $(tput) if your terminal might be weird } inside a TIME_STYLE=+FORMAT to colorize the times.

In `lc`, mentioned a bit this thread, you can actually color the age like a "heat map" if you want. I.e. more recent times are more toward the red side of the rainbow and older ages toward the other "cooler" side ("cold storage"). Or whatever color scheme you like. So, if you know you're looking for something recent, the color pops out at you. If you like that kind of thing.
