There is a way, and it's not hard.

Unfortunately, Intuition has no way of determining the right colors to
use for all the fancy 3D-appearance unless you tell it.

Intuition has several pens it needs definitions for.  In order, here they
are.  (The values used for the Workbench screen are shown in brackets).

detailPen - Same as screen's DetailPen.  Used for things like text in
	the screen title. (Gray on WB)
blockPen - Same as screen's BlockPen. Used for the screen drag bar itself.
	(Black on WB)
textPen - Normal color for text.  This is usually pen 1.  (Black on WB)
shinePen - Color to use for the bright edges of 3D objects.  (White on WB)
shadowPen - Color to use for dark edges of 3D objects.  (Black on WB)
hifillPen - Color to fill active areas, like the border of the active
	window.  Clever gadgets highlight to this color.  (Blue on WB)
hifilltextPen - Text to use over hifillPen.  The title of the active
	window uses this pen.  (Black on WB)
backgroundPen - Background color.  Normally pen zero.  (Gray on WB)
hilighttextPen - A bright text color used on the normal background.
	The preferences editors use this color.  (Blue on WB)

To specify these pens, you need to pass the SA_Pens tag item to
OpenScreenTags().  Create an array of UWORD, terminated by ~0.
For the WB, you would have

wbPens = {0, 1, 1, 2, 1, 3, 1, 0, 3, ~0};

Then you would say

	myscreen = OpenScreenTags(&mynewscreen,
		SA_Pens, wbPens,
		TAG_DONE);

If you want to be 1.3-compatible as well, then you should set
the NS_EXTENDED bit in NewScreen->Flags, and use the ExtNewScreen
structure, which can contain a pointer to the tag-list with SA_Pens
in it.  You can pass the ExtNewScreen to OpenScreen() and 1.3
will ignore it.
