So I installed the Extension from the Pantone Color Mafia
Now I want to Apply that color to the black rectangle. But when I hit the Color Swath, nothing is happening.
How do I make the black rectangle become Pantone 374 U ?
I found the solution:
The pen tool cursor doesn't seem to do anything.
Now it is in the regular color palette of InDesign.
The Choice "+ Add to Palette" is wrong. It adds the color to a palette within Pantone Connect and not InDesign. Seems useless and confusing.
