I’m still trying to wrap my head around the same issue. But, if there’s one thing ive learned, is there is a multitude of variables surrounding the issue. Some of the main variables, as far as ive learned, is water clarity, along with weather/sunlight conditions, and what the fish are eating. Clear water, silver, stained water, gold, then match your surrounding colors with what the fish might be eating. This is just MY hunch from my research. If anyone would like to elaborate or correct any of this info, please do!
