I have just upgraded the "Painter's Guide" app. The major change is the data display dashboard. I have added a new color parameter called the "Tint", which measures how green or purple a color is. As a matter of fact, the color temperature and tint are two orthogonal axes forming a Cartesian coordinate system crossing the color wheel. The conventional hue/chroma polar system and the temperature/tint Cartesian system can be transformed from each other. We artists usually emphasize on color temperature, but not on tint. So we have only 50% of information the nature offers us. After I put the "tint" bar on the data display, the dashboard shows a marvelous symmetry. I was stunned by its mathematical beauty. If something looks good, it usually means something is significant.
The "Painter's Guide" app is a computer tool created by two engineers and myself. It helps artists to see color more accurately. It is also a measurement tool helping us to understand the behavior of the color. The app is free for anybody to use. Please visit: https://www.qhart.com/apps and press the "Painter's Guide 4.0" button. I hope it will help you to make your painting process easier.
Thank you for viewing my art,
