SHADEGUIDEResearch has provided the following insight regarding shade selection. Choosing the degree of lightness vs. darkness (“VALUE”) of the tooth should be the first step. A patient will accept more of an error in actual color (“ HUE ”) than an error in “value”. With this fact in mind, we recommend that you re-arrange your VITA shade guide in the following sequence which is from highest value (lightest) to lowest value (darkest): A1, B1, B2, D2, A2, C1, C2, D3, A3, D4, B3, A3.5, B4, A4, C3, C4.
