Agreed , but the new Norwegian one they gave EBH afterwards was really awesome , and should have been the model for these jerseys too . Would have really stood out in the peloton with the unusual flags that we ' re not used to seeing as often . <| sep |> Thank you for the response ! Basically , I read in an article that said hard and soft nucleophiles will bind to the lawsone molecule found in henna dye at different points . Soft nucleophiles bind to the lawsone molecule found in henna dye in the michael ' s sense michael ' s elimination reaction . If that is true , then it is my hypothesis that solubilizing henna in soft nucleophiles and then applying it to feathershairleather keratin should have a weak dyeing effect on the other hand , solubilizing henna in hard nucleophile and then applying it to feathershairleather should have a stronger dyeing effect because the hard nucleophile didn ' t bind to the lawsone molcule , allowing for the keratin to bind . I was just having trouble getting examples of liquid and polar hardsoft nucleophiles that will solubilize henna powder . I know if I solubilize henna in water , then that would work as a hard nucleophile I am unsure if henna will solubilize in NH 3 which I also believe is a hard nucleophile . I have no idea what to use for soft nucleophile .
