Steve: Would you ask the Essilor folks please: Is there something missing from page 12 of the Tinting manual, under the heading: Basic Color Mixing Guideline, To Achieve: Orange, Etc...? (I'm only in lab a bit, but I do a fair amount of tinting,lightening,or adjusting colors along with inspection and dispense... this manual should be a great help as well as a demystifier!) Thanx!
