Paint collor question

I own a 2011 Cannondale SL4 Trail in green, been using the bike most of the time for commuting by switching to street tires bike is quick and very responsive I absolutely love it. Decided I want to go rigid on this bike, and been thinking of getting niners carbon fiber rigid fork, I would love to match the color but I am not sure if bike manufacturers use the same color schemes? Niners green is called Kermit Green while Cannondale is just green lol. Any one know how to find out? I know car manufacturers keep a track of color codes how about bike manufacturers? Any one? Thanks.
