I have tested alot of colors in the James and Appomattox rivers over the last 15 years. What I found is, mostly it depends on lighting conditions.
As a general rule with soft or hard baits chartruse, something with a golden color or believe it or not orange has out-fished anything else I've used.
Although the bottom line is use what you have confidence in. No confidence in a lure results in not so good results.
