I decided to try and achieve similar results in Bryce as that shown in the link above. Sky: ambient white, sky dome black, shadow intensity 75, haze about 3, sun white Materials: flat color 25 ambience lights: 2 25 intensity squared falloff radials, 1 in front of each window positioned about halfway between the pillar and windows. rendering: true ambience, 64 rays per pixel As can be seen only the walls seem to have picked up some red from the floor. I tried this with just the sun (or even cone light) and couldn't get anuthing even close. What was weird is the back of the column got more light than the side because of it picking up light reflected off the back wall and the corners were even lighter.
