Entrance Colors
 
Entrance supports these colors from  the Tango Desktop Project palette:
 
 
as well as the “usual” colors: RED, BLUE, GREEN  and so on.  Entrance also supports named shades of gray:    WHITE, LIGHT ALUMINUM, ALUMINUM, DARK ALUMINUM, LIGHT CHARCOAL, CHARCOAL, DARK CHARCOAL, and BLACK.
 
Any Entrance color can be LIGHT or DARK, and the standard colors can also be VERY LIGHT or VERY DARK.   Colors can be TRANSPARENT or VERY TRANSPARENT.   For example, a BLACK TRIANGLE completely covered by TRANSPARENT GRAY TRIANGLES will show through them.
 
If these color choices aren't enough for you, use RGB(r,g,b) to specify RGB values in the range 0-255.  You can also specify alpha values using RGB(r,g,b,a).
