I copied a painting of an infamous artist to practice my color temperature control. The warm and cool were varied by mixing proportionally transparent oxide red (TOR) and Portland gray deep (PGD). The objective of this project is to make the color temperature relationship correct for the light/shadow, and near/far fields. With a home-made color temperature metrology, I use my apps to measure color temperature numerically. If I did this project correctly, I should achieve two visual effects: 1, all 3D structures will looks vividly solid with a consistent local color invariance between light and shadow; 2, although I used very low chroma colors (grays), the painting would not look muddy. Please be noted: this is a NOT a monochromatic painting. It has two colors: orange (TOR warm) and blue (PGD cool). I am working in the dark by myself now, but I want to keep you posted.
