Apple AppleVision monitors (OS 7.1) - Manual (Page 62)

The Pantone Match window displays the color you selected for matching in
each of the three standard Pantone color gamuts. The value shown below the
color samples (
ß E*) indicates how closely DigitalColor Meter was able to
match your color with a Pantone color. A small value indicates a better
match.
If you want to identify another color, repeat the above procedure. Otherwise,
close the DigitalColor Meter window to quit the application.
Tips
m If you have more than one monitor, and you move the DigitalColor Meter
window to a monitor other than the one displaying the color you’re
measuring, the color samples in DigitalColor Meter might not visually
match the source color. However, the color space and Pantone values
displayed by DigitalColor Meter will still be correct.
m If you select “Show RGB as Actual Value,” DigitalColor Meter displays
2-byte RGB values. Some programs use 1 byte to represent RGB colors. To
convert DigitalColor Meter’s values, divide by 256 and round up to the
nearest whole number.
