The Test Yourself panel can be used to start a test to visually estimate the composition of a color, using a series of randomly generated colors. After adjusting the color intensities and making a guess, the program indicates whether any intensities must be adjusted up or down (intensities within 15% of the target are considered accurate). When ten colors have been correctly determined, a report is displayed evaluating the performance.
The test may be conducted using the RGB, CMY, or HSV color spaces.
