Clean Line Art
Sketch to Clean Line Layer Workflow
Draw a rough sketch on a low-opacity layer, then create a new layer on top for confident final lines, using the sketch only as a guide — this separation lets you commit fully to clean lines without fear of ruining the composition underneath.
Line Weight & Variation
Vary line thickness deliberately — thicker lines for outer silhouettes and areas closer to the viewer, thinner lines for interior details — to create depth and visual hierarchy purely through linework.
Color Theory Fundamentals
The Color Wheel & Harmony Types
Complementary colors (opposite on the wheel) create vibrant contrast; analogous colors (adjacent) create harmony; triadic schemes (evenly spaced) balance variety with cohesion. Choose a harmony type deliberately rather than picking colors at random.
Building a Limited Palette
Restrict yourself to 4–5 colors maximum for a piece, forcing more thoughtful color choices than an unlimited palette allows — professional illustrators frequently work from deliberately limited palettes for visual cohesion.
Flat Coloring
Color Blocking Under Line Art
Create a color layer beneath your line art layer and block in flat, solid colors for each element — this 'color blocking' stage happens before any shading and establishes the piece's overall palette.
Selection Tools for Clean Fills
Use the magic wand or lasso selection tool combined with a reference line-art layer to fill precise areas without color bleeding outside the lines — dramatically faster and cleaner than manual fills.
The Colored Character Illustration
Create a simple character illustration with clean, confident line art on its own layer, flat colors using a deliberately chosen 4–5 color limited palette, with no bleeding or gaps between fills.
Success criteria: Line art shows clear weight variation between outer silhouette and interior details. The color palette follows a recognizable harmony type (complementary, analogous, or triadic). No color bleeds outside line boundaries.
