I say do it! I had a tiny lobby area on a house I have just sold. I was surprised at how many viewers complemented them. It adds a little ping of interest when the rest of your flooring is "un-patterned" (if there is such a word!) I attach a photo although excuse the spartan furnishings and curtains as some items already removed. You can just about see the tiles in the lobby. I added a couple of the tiles under the electric fire in the foreground for continuity.

Original Style have some beautiful things and you could do well to look there. I don’t work for them and have no connections to them but I’ve found them immensely helpful lately (I live within reasonable distance from their Bournemouth store). My first encounter with them was about 20 years ago. (And ask for a discount…you never know! )

Can you post some photos? https://www.thekitchenthink.co.uk/how-to-avoid-terracotta-tile-tragedy/ https://www.thenordroom.com/terracotta-floor-tiles-modern-home/ I think the above article is brilliant. Terracotta with lots of earthy browns will give a seventies vibe, whereas with paler taupes and whites will look crisper and more modern. Pure white may look harsh so pale taupes are always a good bet. Grey was virtually unseen in the 70's so any kind of marble, or greys can work well with terarcotta as it can't then look 'retro' if this makes sense. It can feel 'heavy' especially with other dark colours so lots of paler elements would work.
