Depends on the body of water. If you’re looking for a cut-and-dried answer like, “cold front use spoons, warm use raps, cloud use spoons, etc” there isn’t one.
A wise man (and great outdoorsman) once said that nothing drives a statistician insane like a fisherman. They’re always looking for and finding patterns where they don’t exist. Example: they’re hitting blue today, when really you just happened to have blue on during a feeding window when they may have hit any color. From then on, it’s a confidence thing and you’ll think blue is key in that body of water. If you never use green, but decide to give it a shot one day, you probably won’t stick with it as long and draw the conclusion that it doesn’t work on that body of water (and that’s usually only when blue didn’t work first, indicating negative fish to begin with). It’s an endless cycle of confirmation bias. You see it with raps all the time. People don’t use them enough to learn how to use them properly, thus they never find the success, thus they think they don’t work, so they use them less, etc.
I always try let the fish tell me. I like to start with rippin raps because they can pull fish in. If they’re not interested, I’ll change until I find something that they’ll eat.
The one thing I do know for sure is that there isn’t anything more fun on the hard water than getting a school of riled up walleyes crushing Rippin Raps.
