A yellow triangle with a single unblinking eye stares out from just about every corner of the Gravity Falls fan art world, and this guide walks through how to draw Bill Cipher in a way that breaks that geometry down into something manageable. Nine steps cover the full character, finishing with a colored result.
Breaking Down a Triangle That Looks Simple but Isn’t
The tutorial runs 9 steps and ends on a fully colored version, so the final step shows how the yellow body and brick texture come together with color. The trickiest part is getting the proportions of the triangular body to feel right before layering in the eye, hat, and limb details. Because the character is built on pure geometric shapes, small errors in the triangle read more visibly than they would on an organic figure.
Bill Cipher’s Key Visual Features
- Triangular yellow body with brick pattern
- Single large eye with slit pupil
- Black top hat at the apex
- Black bow tie on center body
- Stick arms and legs with claw hands
If you are working through the Gravity Falls cast, the site also has Stan Pines and scared Mabel as separate sketch guides, plus Little Gideon for another antagonist to practice alongside Bill.
Understanding the Step Color System
Each step image uses a three-color system to show exactly what is new and what came before:
- Red Color: lines added in the current step.
- Black Color: lines completed earlier.
- Gray Color: base sketch for structure.

Once the coloring is done, drop your finished Bill Cipher in the comments. Seeing how different artists handle the yellow and the brick texture is always worth a look. New tutorials go up on Facebook and Telegram as soon as they are published, a new YouTube video based on existing guides posts every single day, and Pinterest gets updated regularly too. From the rest of the Gravity Falls lineup, Mabel Pines with Waddles and Gompers the goat are worth tackling next.
