After season (I did this last week) I soak all my fadded camo's in green dye. A small amount of the stuff put in a 5 gallon bucket 2/3's full of hot water. Stir it in and let it sit.
Mine sat overnight- in no hurry.
They will come out greener. Everything will be greener. I mostly bowhunt in the tree's when it's green, so greener is better than fuzzy white to my eyes.

A total waste of time I'm sure, but what else do I have to do hunting wise with 130 some odd days till season starts .

You may consider using brown if your camo's favor a brown color.
