Ok so I've been taught that in clear,sunny conditions that a silver bladed spinnerbait is best.

In cloudy,low light situations,gold blades will work best.

What about days where its sunny and then cloudy off and on throughout the day.

Which blade color choice is preferred on days like these? Do you have 2 different poles rigged up?

Oh and in what condition does one use painted blades,ideally?

As everything else in fishing there is really no rule but for me spinnerbaits are special so I'll tell you how I select blades. First off you are right, sunny=silver or nickel, cloudy= gold or brass and it works well but that is based on clear water so for clear water with periods of sun and clouds I'd go with gold since the sun doesn't hamper the gold as much as clouds dull the flash of silver blades. If I'm fishing water that is stained but still has 3' of visibility I'll go with gold indiana blade unless there are smallmouth and then is when I like to have a painted blade, either a chartreuse or white blade. The reason I like the painted blades in stained water only if smallies are present is that they seem to react more to color than a largemouth does, it isn't to say I never caught a largemouth on painted blades because I have but I up the odds at catching smallies on the painted blades. I stay away from those painted blades pretty much in clear water but there is an exception and that is low light days, most of the time I use the gold or brass blade for that kind of day but sometimes I will use metallic colored blades, a metallic chartreuse with a metallic blue or metallic red, these put out flash on low light days just good as the brass or gold and I only do that just to change it up and see if it affects the bite at all and for the most part they hit the gold blades just as much as the metallic blades so either blade choice is fine.

Clear: silver

Light stained: Gold/silver combo

Stained: Gold or white turtle back

Muddy: Copper hammered.

That system has worked for me for a long time. I have fished a painted red/back blade on specific waters but that's a rare occasion.

Since spinnerbaits seem to haul water for me around here anytime the sun is out when the water is clear, even if it is blowing, I tend to toss them only on cloudy days and/or in stained water, so I use gold most of the time. If it's really overcast I use painted blades. That's specific to one body of water, on others I have used silver and done better.

I usually don't worry about blade color for weather conditions... Usually blade color for me is a concern based on water clarity. Silver for clear water and gold for stained. I concentrate more on body/skirt color for weather. I usually go with white/silver (light colors) on sunny days and black/dark blue (dark colors) on overcast days.

Cloudy=gold

clear=gold

early=gold

midday=gold

late=gold

cold water=gold

warm water=gold

I will throw a silver one on December 21st, just in case the Mayans were right...

Dual willow blades with one of each.
