Query: I thought chocolate was BROWN!

I have dark brown hair and usually use that to cover gray hair. I thought chocolate would be a lighter shade of brown but the gray hair turned out an orangey red copper. It looked awful with my light olive toned skin. It took 2 more tries with dark brown to get rid of the copper. Well now I know. Maybe this will be useful to someone else.
