Command execute in the item hand

Hello all I would firstly like to prevent that I am originally a French so I use google translation. So my problem is that I wish that when the player clicks on a red dye he executes the command / red which will have been previously made in another class and how to make it checks whether a red dye but with a custom name for if not with any red dye, you'll be able to do what we want. thank you very much

Merci beaucoup
