If I'm reading what you're saying right, you cold smoked for 10 hours, and you got very little color & not much flavor.
I agree with David about giving it more smoke, and if you look what I said in my post #7, I gave you two methods to get good color & good flavor. You chose to cold smoke, so you should have given it at least 24 hours of cold smoke. The only way you can get great flavor & color in 10 hours would be with a little heat. IMHO
