Multicoloured wedding decor - would it work?

Hi, we're having our reception in a big marquee surrounded by fairy lights outside, but its a big space and we're nly having 60 guests (so 8 tables and a head table). I've been debating colour schemes and I want to bring some colour to the white space. I was thinking about having a multicoloured decor/seating plan. So each table is assigned a specific colour and then the decor on the table matches the vibe. So one table could be green and it would be white linen and a green table runner, then they'd all have matching centerpieces but each one would have a few extra flowers in that match the colour scheme. Do you think that would look awful? I'm struggling to visualise it in my head. Other than that the only other decorations I have planned so far are white blossom arches behind the head table and bar, and some blossom from the chandelier type lights.
