arrows below the 3D picture. Each ball and arrow correspond to 1 of 64 Munsell papers measured by Vrhel. The center of the ball is the paper's stimulus vector under daylight. The arrow tip is the stimulus vector under High-Pressure Mercury Vapor light. Tristimulus vector of Mercury Light = [3.751, 0.03204, 1.389]. Tristimulus vector of dayight = [3.751, 0.03474, 1.396]. High pressure mercury vapor light was measured by Worthey in 1985. Daylight is calculated by the model of Judd, MacAdam & Wyszecki. All points are plotted by detailed calculations, no simplifying assumptions. |
