What you posted is the basic info most folks start with. But figuring out what bait color and size bait that is best for the water color at that moment (and speed). Using that info can be daunting. And most fisher folks after time find colors and baits that work for them and when.
Experience of what colors are preferred where/when. Let alone what baits and type/shape work best at what time of year in the area's you fish. And all the custom colors, all together can cause alot of time wasted time changing baits and colors. Less actual fishing.
Some basic's would be silver/blue, perch/green, purple/pink early season and into warming waters. Once the water starts to warm up. Into summer, silver/blue, purple/pink can produce better results. Different years, the colors can also change due to what happened to Erie over the past year. Lots of variables.
I'd suggest figure out where/what depth and what speed the fish want first. Then dial in what color produces best. Color would be the last fine adjustment to a successful trolling pattern for the day.
Tomorrow that may very well change.
Some baits work for some, not everyone. Find ones that work well for you and will have confidence in and work with those till you get more experience. Don't go crazy buying alot of baits. Till you get/have more experience. That will save time and money in the long run.
To shorten the learning curve. Take a charter or fish with others. You will learn more in 1 day of fishing with experience than a summers worth of trying to get dialed in on your own. IMHO
There are just so many little things that experienced fisher folks due at any given condition to improve the catch. Those typically don't get mentioned or thought of till someone asks a question. You will be able to do so. Why that color, why the speed, the direction of the trolling path etc that all relate to the conditions at hand. (take notes!)
