Colorimeter window
The Colorimeter tool allows measurements of colors displayed on the screen to be taken with the calibration sensor,
and is accessed from the Tools menu. The measurement results are displayed in a variety of useful formats.
To take color measurements using the Colorimeter, place the calibration sensor to the screen so that it is centered on
the large white area in the Colorimeter window.
Measure:
• Single - clicking this button will take a single color measurement and display the results.
• Continuous - selecting this will take repeated measurements automatically and display the results.
The CIE XYZ and xyY fields show the calibration sensor's measurements translated into each of the respective color
spaces. These color spaces are device independent color spaces, which means that they are not relative to any specific
device, as opposed to dependent color spaces, such as RGB, which is relative to the device that is displaying the color.
The Color Temp field shows the corresponding correlated black body radiator temperature of the measurement in
Kelvin. The Δuv (Delta-uv) value indicates how far the measurement is from the black body radiator locus. The Kelvin
value is only meaningful for colors that are near the black body radiator locus, such as most shades of white.
Sample Color: By selecting this group a custom color can be shown in the measurement area. To interactively adjust
the color, click and drag within the color circle or use the arrow keys. Use the vertical slider control to adjust the Intensity.
Specific Red, Green and Blue values can also be entered.
