Andrew, try this code below. It's a fantastic flame, and a flame that I
might even try [again] even though it's getting late now for the IRTC...
This flame gives off its own light, and you might be pleasantly surprised
with it.
#version 3.5;
camera{location <0,1,-8>
look_at <0,1.5,0>

SmallFlame // you have to include this line in pov sdl for it to work
Give it a try.

Actually, I like the lighting the way it is. The floor in the shadow of the
large candle edges. The colour of the candle light still needs some yellow
or orange tingin to it though. And to make your candle more convincing (I
don't mind the shape or texture of the candle itself) you need a slight
waxy hollow in the top where the flame has started to melt the wax. (and a
better flame). Overall, you have a good scene composition, all you need is
a little tweaking on the lighting, and little more on some of the
texturing. For the background texturing of the box itself, the textures
you have been using may be fine, but you need to scale them down in size to
give the scene better overall scale perspective.

You're probably right. Adding the extra blue light makes the floor less
dark and the candle less brown, but also makes the light it casts look
less yellowish. (And the dark brown wood probably doesn't help.)
Getting the balance of warm to cold colours is proving to be a challenge...

The flame is probably the easiest part to fix. (Which is why I haven't
bothered with it yet.)
A pool of molten wax would be good, but I'm really not sure how to
achieve it. (It took me hours to figure out the equation to make a
round-topped cylinder!)

The candle and box are supposed to be quite small...
