Lighting help please

I’ve been having a little problem with this abstract model i’m working on. I’m trying to make the cube that surrounds everything a perfect white colour but when i change the color settings it just turns grey, i’ve also been trying to do this with lighting but whenever i try this, it just turns the whole image a really bright white. can anyone help? image below.


turn on the emit value in shade panel
taht will increase the whitness of your cube!


that worked perfectly thank you

Probably a last resort this one, but you can ‘Add’ Colour Ramp colours. Try it with Mix first though.

EDIT - Darn, too slow!
