I like it. If you go with what you like and are happy to live with it, who cares that it will "date" it's your home not a fashion magazine.
Our kitchen is about 8 years old and "dated"; wooden units, multicoloured tiles. But then if we'd jumped onto clean lines, gloss and grey, that would be dating rapidly too and worse because it's a strong fashion rather than a more traditional "classic". I don't care as it's warm, sunny and homely.
Pastels and minimal lines was more 50s than 70s. I grew up with a lemon kitchen from the 60s, and nicer than the beige/ wooden trims or dark woods that were being installed at that point in the 80s.
