How detailed are your lab Rx forms for anterior cases?

Had a veneer case come back with the wrong value (too bright) despite sending photos and a shade tab pic. **What I currently send:** - Prepped photos - Shade tab photos in same lighting - Written shade (e.g., "A1 body, slight A2 cervical") **What went wrong:** I said "natural" and lab interpreted that differently than I meant. **Question:** What's on your lab Rx that you've found actually makes a difference? Anyone have a template they're willing to share?
