As for the gel color, Jeffs (Sonik) Viper is an original apricot. Not sure what it would take or what colors are needed between the base and the flake to get the color right.
As for the "hook", the original hook, isnt actually a hook but rather a wedge. Dont get rid of it if yours has it. I know the Vectors have them but not sure if the vipers do. If they do, its the later ones. You can tell where the wedge is. it will have a slight angle to the back 1/4 of the pad then flatten out. An unwanted hook will be a constant curve in the pad. In the picture you can kind of see the factory wedge. This is from a Vector.
