OK, so you can't actually SEE the nudity, but it is there!

Anyway, I'm so pleased with the bits of Vue4 Pro that do work, I've decided to stop failing to make animation and try to make my first static scene.

What I'm trying to acheive is a lovely, golden summer morning colouring. I've heavily tinted the only two light sources here (1 point, 1 quadratic spot) with a golden yellow, even tinted all the materials yellow. It just comes out greeny-blue whatever. Suggestions?

TIA
