Values in Bartholomeus Spranger rest in the mid-range - neither dramatically lit nor steeped in shadow. Bartholomeus Spranger orchestrates warmth above all else - reds, ambers, and siennas take the lead. All colours lean toward grey, building depth through value rather than colour punch. The saturated accent, #B93319, registers at 1.9% - sparse enough to feel like a deliberate surprise. The value range of 51 units sits in the comfortable middle: enough depth, enough light, neither extreme. Palette 4 sits within the larger chromatic argument that Bartholomeus Spranger's complete body of work advances.
