D32 (black body: 3200K)
D33 (black body: 3300K)
D40 (black body: 4000K) halogen lamp without filter
D50 (black body: 5000K)
D55 (black body: 5500K) halogen lamp through CB filter
D65 (black body: 6504K)
D68 (black body: 6800K)
D73 (black body: 7300K) metal halide lamp
D95 (black body: 9500K)
CIE standard illuminant A tungsten lamp

After selecting observer and illuminant, push `OK' button to display the interference color chart in the new window.

To hide the interference color chart, push `Dismiss' button at the top of the chart window. To terminate the program, push `Exit' button.

ColorSync profile

Simplest way to use the profile is as follows:

  1. Use a QuickDraw printer. If your printer is not a color Postscript printer, you may use a QuickDraw printer.
  2. Start ColorSync in the control panel. Press `profile' tab and select `CIE RGB color space....'
  3. When you print a interference color chart, use the ColorSync for the color-matching. Details may be described in the manual of your printer.
