I'm getting six veneers placed on my upper teeth. Yesterday I had to pick a veneer color. I wanted BL2

my dentist said my bottom teeth are at about a BL3 and that I should go for BL3. The tech recommended I go for BL4 and I stressed to her that was FAR too dark since I'm going for the Hollywood bright smile. I'm also very pale and 30 years old. She then said OM1 with OM2 and then OM3 at the root. Now I'm having a difficult time trusting that the tech is on the same page as me. I plan to get veneers on my bottom teeth in the future. Will the this combination give me a smile with a hollywood bright smile?
