What color is the wall? To be illuminated by blue light it must have
blue in it. If its color has only red and green (orange) it can not
reflect blue and will render black (or that suplied by the ambient
light).

No, the wall material does reflect blue – when I turn on the light's OVERSHOOT
button, the whole wall ends up blue, but without the proper shadows…
