The Complete Rainbow Edit
Our Rainbow collection started with a simple idea: make it easy to shop a whole theme in one go. With every colour of the rainbow in one joyful collection running through the range, it's a genuinely useful starting point for a rainbow-bright celebration, whatever scale you're planning at.
Tips for a Standout Rainbow Celebration
Photos tend to focus on eye level and above, so don't skimp on matching balloons, banners and tableware near the main table or entrance — that's usually where a Rainbow theme gets noticed first, before guests even sit down.
If you can't decide between two colourways within the Rainbow collection, it's usually safe to pick both and split them across different areas of the room — one for the table, one for the entrance or backdrop. It reads as an intentional choice rather than a clash.
Behind every Rainbow product is a small team that actually plans parties themselves, which is why the collection is built the way it is — around what's genuinely useful when you're up against the clock, not just what looks good in a catalogue photo.
Shop the complete Rainbow collection below and let Tara’s Wonderworld help you turn your theme into reality, one detail at a time.
