I don't get orange hands, but I do get orange nails. I make sure I wash it out well with conditioner. The second time I even used a little elucence shampoo. I find that even when you think that you have it all out it's still not all out. I don't know what can be done to be honest.
I checked out the pics and your hair looks great!
I'm thinking about doing my third this weekend and I made up a batch of henna gloss that I'm going to play around with.
