[Visualpython-users] Color / Intensity Question

If I specify the color of an object in the RGB format.  Now
suppose further that I have a specified ambient light in the
scene.  If I raise the ambient light in the scene, the object
gets brighter.  Is the signal in the RG and B channels the same
for the brighter object.  Does the additonal brightness end
up as some scaling factor on another channel?

Related question.  If I specify the graphics height and width
to be a certain size, does that include the border around the
scene?  Can that border be turned off?

Thanks in advance,
