01 What It Does

Illustration Style: Define a Visual Language

Define an illustration family’s visual style, palette, characters and use across product screens.

Source-based workflowNot an execution benchmark

The Working Approach

Illustration Style specifies how a family of illustrations should look and where it belongs. It addresses geometric versus organic form, flat versus dimensional treatment, detail level, abstraction, and line style.

The source connects that visual language to product color, optional character rules, and different contexts such as hero imagery, empty states, onboarding, and errors. It also asks for reusable elements and creation guidance. This is an art-direction specification, not an image-generation model or a finished asset pack.

Expected Deliverables

Palette, character, and reusable-element rules
Context-specific application and accessibility guidance

See the Example Brief

From Brief to Review

01
Define the Style Axes
Choose form, dimension, detail, abstraction, and line treatment with concrete references.
02
Set the Family Rules
Limit the palette, define shadows or gradients, and add character guidance only where relevant.
03
Map the Applications
Explain how hero, spot, empty-state, and other illustrations differ in scale and purpose.

02 When to Use It

When to Use It

Use it before commissioning a series or when existing product illustrations need a consistent visual direction.

A Good Fit

Commissioning a SeriesGive contributors enough constraints to produce related artwork.
Inconsistent Product ImageryAlign illustration families without forcing every context into one identical composition.

Limits to Check

Not an Image GeneratorThe documented output is guidance; finished artwork needs a separate creation process.
Not an Icon StandardSmall symbolic UI iconography has a separate system specification.

Bring These Inputs

Brand ReferencesSupply product colors and accepted visual examples.
Application InventoryList the surfaces and sizes where artwork appears.
Content NeedsIdentify concepts, characters, and representation requirements.

03 Decisions That Matter

Decisions That Matter

Consistency With Range
A shared language can support several illustration types without repeating the same scene.
Purposeful Placement
Usage rules explain when illustration helps and when it becomes unnecessary decoration.

Review the Setup

Load this task's SKILL.md from the designer-skills repository in your agent's supported skill location. No universal installer command is established by the entry file.

Upstream Source File

https://github.com/Owl-Listener/designer-skills/blob/9a6930cf84a822eb458624bd11c61aac5bbdf224/ui-design/skills/illustration-style/SKILL.md

Provide approved visual references and the places illustrations will appear. The skill produces art-direction guidance, not finished images.

Start With One Deliverable

Adapt the scope, source material and constraints in this brief before running the skill.

Example Brief

Use illustration-style to write a guide for our onboarding and empty-state artwork. Define shape, dimension, detail, line, and palette rules; include dark variants and representation guidance where characters appear. Specify display-size checks and text alternatives without claiming that assets have been generated.

Inspect the Result

Check the actual output against these observable criteria.

Style decisions are concrete enough for another illustrator.
Each application has size and purpose guidance.
Essential information is not carried by imagery alone.

06 Questions Before You Start

Questions Before You Start

Does it generate finished illustrations?

No. It produces a style guide; finished illustrations need a separate creation process.

Must every style use characters?

No. Character rules are explicitly conditional.

Should hero and empty-state art be identical?

They can share a visual language while following different scale and communication requirements.
