I'm painting my walls Brilliant White. What color do you think would look best for my skirting boards/base boards ?

Dark, forest green

The style here in the my area seems to be white walls and white baseboards.

And you're right in style, black furniture is the trend here too. Beautiful.

I like rooms to be bright and cheerful, so whatever color makes you the happiest would be my choice. :)

Leather?

White. Flat for the walls. Gloss for the trim. Always in good taste.
