A word describing the a mix between new & old

I have a website that discusses modern technology however as part of that site I focus on vintage colours & styling. Months back I had a visitor describe it as X. I can't recall the word they used but it was a word I hadn't heard as an English native before.

Perhaps the word heard was, from Lexico

retro
ADJECTIVE

Imitative of a style or fashion from the recent past.

The result is a car which is both modern and retro in its looks.
The style is heightened by the restrained color palette and decidedly retro feel to the animation.

Eclectic: The eclectic home decor, with it’s baroque-styled gold-leaf framed antique mirrors juxtaposed to slate grey-travertine LVT floors, was a study in home decorating epochs.
