Our tree is only adorned with blue and white/silver decorations - it's the rule. And those baubles also feature.
The lights are all white/white-ish however, and are on "Just on - the classic - no flashing, strobing or fading" mode.
I'm sensing a slight shift back to multi-coloured lights this year, and I like it.
It's been mainly white for a while with the upstart blue becoming more prevalent over the last few years.
