The image's selected colors do not convert

Question

When adding an image to a worksheet, I extracted all unique colors, then graphed the list. Everything good so far, but when I select 'vectors' and choose an ICC profile, the graph displays nothing. Is this a bug, or am I misunderstanding something?

Answer

This issue stems from how the Worksheet handles conversions. When a profile is added to an image with selected colors, only the image data is converted by the profile. The selected color list is left alone.

For what you are trying to do, the solution is easy. After making your selected colors list, choose "Use as Primary Data Source" in the 1st column's color list PRIOR to applying profiles or graphing, and the color numbers will be converted correctly.


Question

Why won't the Grapher graph my Device Link profile?

Answer

With a device link profile, there is technically no gamut because DL's represent a direct connection between color spaces. However, you can use ColorThink Pro to view the results of a device link profile:
