When making a color chart with device colors on neoStampa Delta and editing a color, both the color picker and "Measure" buttons are disabled.
The reason is multichannel color spaces have no HSB representation.
In order to get device colors represented in the color picker, select "Output profile colorspace". This option shows a picker and returns picked-up colors as RGB values within the printer profile. For more details, see How to print RGB color variation charts from neoStampa.
