There's a reason the pack doesn't deviate too far from the default colours: so it can look good for everyone. It makes it a lot tougher to build with if your pack looks different to everyone else's. I know Tsar in particular really likes the slightly metallic clay shade of grey. Think how silly the Burj would look if clay was red.
At this point, changing colors of any of the commonly used blocks would make many structures look messy and strange. It is best to leave them as is and adjust nearly unused blocks instead.
