I agree that the colours are not nice. I'm doing a new rendering now,
with the crackle pattern, where I have given all the spheres a light
blue
pigment.

And with a light source that fades with distances, this makes the
colours of the spheres to vary from deep blue to almost white.

I let the iso-surface do the work itself.
(-By using a pigment function inside an if statement. If the pigment
value in the middle of a "subcube" in 3D-space is above a certain
limit/threshold, a function is called to make a sphere in this
"subcube".
Else a constant outside the limit is returned.)

Unfortunately I have lost the source code for the image I posted,
but I'll soon post the code for the new image I'm rendering.
