Just to be clear, I'm not suggesting that my example is a good way to
code a solution. It just illustrates how UpdateNow would allow the
first color to be seen onscreen before the second color overdraws it.
That wait loop is a total waste of CPU cycles...

Additionally you need to allow some time for your first color to
register in your viewer's eye/brain before changing to the second
color. Otherwise nothing will be perceived even though the first
color showed for a brief period. Here's an updated method that shows
how to do both...
me.graphics.ForeColor = RGB( 20, 80, 160 ) // BLUE
me.graphics.FillRect(0,0,me.graphics.width,me.graphics.height)
Window.UpdateNow //Flush the Blue rect to the screen
Dim DoneTicks as integer = Ticks + 30
While Ticks < Doneticks
//Allow the blue rect to linger for half a second
Wend
me.graphics.ClearRect(0,0,me.graphics.width,me.graphics.height)
me.graphics.ForeColor = RGB( 160, 80, 20 ) // ORANGE
me.graphics.FillRect(0,0,me.graphics.width,me.graphics.height)
Hope this helps,
Joe
