which colors for a frame3d ?

Hi, maybe this will seem a little stupid, but...
I want to represent small square tiles
(in green, red, yellow, blue and dark gray)
on a light gray background.
I would like to add a little 3d effect and I've
seen that maybe the Drame3D function can help:
Frame3D(Graphics::TCanvas * Canvas, Windows::TRect &Rect, Graphics::
TColor TopColor, Graphics::TColor BottomColor, int Width);
That function draws a 3d rectangular frame using two
given colors. To obtain a 3d effect I have to
fill the square with my color and then call frame3d with
a lighter and a darker color.
Now the question:
is there a mathematical formula to compute (in a consistent
way across tiles of different colors)
the rgb components of a ligher and darker color of a given color?
