Picking a Grapher element works for color lists and profiles in the Grapher.
Color lists:
Picking a color list will display information present in the color list file, such as device values, Lab values.
Profiles:
Picking a profile will display the name, the type of ICC profile, the color space and any details concerning how the profile is displayed in the Grapher.
Images:
Picking does not work for pixels of images brought into the Grapher. However an image can be opened into the Worksheet, and then be sampled using a grid or by extracting unique color values to create a color list. This color list can then be opened into the Grapher for Picking.
