Each season new colours come into fashion. If you need new towels or bathmats, facewashers, hand towels etc do you try and get a colour that matches the ones you already own, or do you just get the colour you like?
I get the colours I like, but that sometimes mean they end up matching by accident. That's just the bath mats and hand towels though. The kids' towels are in the colours that they prefer (currently bright yellow for my son, hot pink for my daughter).
I currently have a mix of colours and when they're all on the towel rack in the bathoom they look dreadful together! We plan to renovate the bathroom in the next year, and when we do I'll settle on a colour.
The kids have their favourite colours for their own towels.
