What is Rainbow in Knockout?
Rainbow in Knockout is a special visual effect that applies a vibrant, color-changing appearance to your character or weapon. This effect is highly coveted by players due to its rarity and eye-catching appearance. When equipped, your character will cycle through the colors of the rainbow, creating a stunning visual that stands out in the game.
The Rainbow effect was introduced to Knockout in a limited-time event and has since become one of the most challenging cosmetic effects to obtain. Unlike standard items that can be purchased directly from the shop, Rainbow requires specific achievements or gameplay milestones to unlock.
There are actually several variations of Rainbow effects in Knockout:
- Full Body Rainbow – Affects your entire character
- Weapon Rainbow – Applies to your equipped weapon
- Partial Rainbow – Covers specific parts of your character
- Rainbow Aura – Creates a color-changing aura around your character
Each variation has different requirements, which we’ll explore in detail throughout this guide.
Prerequisites for Obtaining Rainbow
Before attempting to unlock Rainbow in Knockout, you’ll need to meet certain prerequisites. These requirements vary depending on which Rainbow effect you’re aiming for, but here are the general prerequisites:
- Account Level: Most Rainbow effects require you to reach a minimum account level (typically level 50+).
- Game Progression: You must have completed specific game modes or challenges. For Full Body Rainbow, this usually means completing all standard game modes at least once.

- Time Investment: Be prepared to invest significant time into the game. Most Rainbow effects require at least 50+ hours of gameplay.
- Specific Achievements: Certain Rainbow effects are tied to completing specific achievements, such as winning 100 matches or achieving a specific kill/death ratio.
