It is the character every Rainbow Friends fan knows first. Episode 70 of the 6-minute 100 Days Sketching Challenge captures Blue's distinctive silhouette and unsettling blank expression in a step-by-step guide any kid can follow.

How to Draw Rainbow Friends Blue Step by Step

  1. Draw the body shape — Blue has a very large rounded teardrop shape, significantly wider at the top than the bottom. The upper portion is like a wide dome. Blue is the biggest of all the Rainbow Friends characters.
  2. Establish the eye placement — lightly mark where the eyes will go: upper-centre of the body, close together. Blue's eyes dominate the upper face area.
  3. Draw the eyes — two very large oval shapes, side by side. Blue's eyes are enormous relative to the body — make them almost one-third of the total body height each.
  4. Add iris detail — inside each oval, draw a large coloured iris (a slightly smaller oval). Inside the iris, a black pupil circle. Add a white highlight dot in the upper area of each iris.
  5. No mouth — this is the most important step. Blue has absolutely no visible mouth. Leave the lower face completely blank. This blankness is what makes Blue disturbing.
  6. Draw the arms — two wide, rounded arms hanging down from the sides of the body. They are relatively short and end in rounded stubs — no fingers.
  7. Add the legs — two short, rounded legs at the base. Blue moves in a slow waddle.
  8. Colour and shade — solid royal blue throughout. Add very subtle darker blue shading on one side of the body for depth. The eyes remain white with the iris colour inside.
💡 Parikshet's Tip: Blue's most disturbing feature is the completely blank lower face — no mouth, no chin line, nothing. When drawing, actively resist adding even a hint of a smile line or any mark below the eyes. The emptiness is the point. A mouth would make Blue friendly; the absence of one makes it threatening.

🌟 Did You Know?

Rainbow Friends was created by Roblox developers Roy and Hex (the development studio CHROME TREES) and launched in June 2022. It became one of the fastest-growing Roblox games of all time, reaching 1 billion visits in just a few months. The character designs were deliberately created to be simple, colourful, and memorable — easy to recognise and recreate by the young fan community.

Why Blue Became the Face of Rainbow Friends

Among all the Rainbow Friends, Blue became the most popular and recognised for specific design reasons:

  • Simplicity — Blue's design is the simplest: one colour, rounded shape, eyes-only face. Easy to draw and remember.
  • Size — Blue is the largest monster, which makes it feel the most threatening.
  • The absent mouth — a face with only eyes and no mouth is deeply uncanny. Our brains struggle to read emotion from it, creating unease.
  • Colour — blue is associated with calm and trustworthiness in most cultures, making Blue's nature as a monster feel paradoxically wrong — which adds to the horror.

🎯 Try This: Draw Blue in Three Moods Using Only Eyes

  1. Blue has no mouth — so its only expressive feature is its eyes.
  2. Draw Blue three times with different eye expressions: eyes wide open (neutral/staring), eyes narrowed (suspicious/hunting), eyes looking sideways (sneaky).
  3. Notice how much the eye direction and size changes the character's feeling, even with no other features changing.
