I did some color research lately. This video shows I mixed ultramarine blue and white together, and then analyzed this "tinting" process with the "Color Analyzer" app. This app is developed by two engineers and myself. It is located on my website: https://qhart.com. You can access it by clicking the "Apps" tab, then click the button "Color Analyzer". It is free for anyone to use. Via this experiment, I have discovered that adding white to ultramarine has actually changed its hue toward turquoise. This result has violated my theoretical understanding. I thought that tinting should not change the hue of the color but only increases its value and decreases its chroma. In other words: it should be a straight line toward the center of the color wheel. I have found that is not the case. I don't understand why this happens, but I must accept the experimental result from the scientific point of view.
