C&H From color values
For Mac
Press the Shift key and click inside the sector. When the pointer changes
to a Hollow Cross, drag the sector to a new position.
For PC
Press the Ctrl key and click inside the sector. The pointer now turns into
a Hand pointer, then drag the sector to a new position.
You will see that the sector can only be expanded or contracted in a
limited fashion, as it is constrained by the position of the hollow dot. If
you need to move the sector around, you will also need to reposition the
hollow dot, which then changes the Chroma and Hue (C&H) values.
