Because I do not need the dict setColourScheme anymore I changed it
to:
    currentdict setsetColourScheme [/gradient1 /gradient2 /textColor] getDictValues
    (after getDictValues) ==
    pstack
    currentdict setColourScheme undef
    (after undef) ==
    pstack
    setColourScheme /gradient1 get
    (after fetch) ==
    pstack

The == and pstack are to check. I get:
    (after getDictValues)
    (after undef)
    (after fetch)
    {colorForestGreen}

So setColourScheme is not deleted. Why not?
