Heartopia Rainbow Event — Prismatic Furniture and Rewards

The Heartopia rainbow event ran from April 10 to May 10, 2026, as the game's first seasonal event. It introduced prismatic furniture — items that shift through color cycles — and rainbow flower cross-breeding. While the event has ended, this guide documents what was available and what might return. XD has hinted at yearly event reruns.

Event rewards recap

• Prismatic furniture set: 8 items including a bed, table, chair, lamp, and rug that cycle through rainbow colors.
• Rainbow outfit set: 7 pieces with a gradient dye pattern. Still considered one of the best free outfits.
• Double XP weekends: all hobbies earned 2x experience during the event period.
• Rainbow flower seeds: exclusive cross-breed line with impossible color combinations.

Rainbow flower cross-breeding

The rainbow flower was a special hybrid created during the event. Plant red + blue flowers in adjacent plots with a specific spacing pattern to get rainbow petals. Rainbow flowers could be crafted into prismatic dye — the only way to get animated color-shifting outfits. The flower seeds are no longer obtainable, but plants from the event still grow if you keep them watered. Players who missed the event can buy rainbow flowers on the market board from hoarders.

Seasonal events run on a repeating cycle. XD has confirmed the rainbow event will return in 2027 with new items. Check the Seasonal Events guide for the full calendar.
