Rainbow balloons bring every colour at once, brilliant for a kids' party, a Pride celebration or any bright, cheerful theme. Buy a mixed multicolour pack and build a rainbow arch, or scatter the colours around the room. Send the look ready-made with an ombre and rainbow balloon in a box, or build your own from the wider balloons range. Running the colours in rainbow order along an arch, red through to violet, reads far better than a random mix, and matching multi-colour party supplies keep the rainbow going across the table.
