Character design is the secret ingredient that brings illustrations to life, guiding readers to instantly recognize and emotionally connect with each figure. In book illustration, the design of characters offers more than visual appeal—it builds personality, mood, and story dynamics, all at a glance. Especially when designing characters for children’s books, thoughtful visual choices create engaging moments that resonate deeply with young minds. By harnessing shape, color, posture, and expression, illustrators weave intricate layers of narrative through art alone. This introduction sets the stage for an in-depth look at how character design drives visual storytelling and enriches readers’ emotional journeys.

What Is Character Design?

Character design is the art of visual storytelling, crafting a character’s appearance, personality, and role through intentional choices in shape, color, silhouette, and expression. It begins as a concept—personality traits and behavior—then evolves through sketches or digital tools into a compelling visual representation. Effective character design combines artistic flair and psychology, using silhouette to make the character instantly recognizable, color palettes to evoke emotion, and exaggeration to emphasize key traits.

At The Rainbow Stories, these design principles are at the heart of every illustration project.

Visual Character Traits & Role in the Story

Designing Characters for Children’s Books

When designing characters for children’s books, illustrators draw hundreds of rough sketches to explore shapes and expressions. Alexandra Thompson notes that designers test eye size, costumes, and color combos to ensure each character is visually distinctive yet reproducible over dozens of pages .This process is one of many tips shared by experienced Book Illustrator professionals.

Character Design & Book Character Personality

Crafting book character personality visually requires decisions that hint at personality traits and internal growth. From expressive eyes to clothing choices, thoughtful character design helps characters resonate emotionally. Interpreting a child’s introversion versus extroversion through posture or color can spark empathy.

Visual Storytelling: Shapes, Colors & Emotion

Good character design also employs visual tools like shape psychology and color theory. Claire O’Brien advises designers to consider physicality, shape, and storytelling: rounded forms suggest friendliness, triangular shapes hint at conflict, and color tones convey mood—all enhancing visual storytelling.

Engaging Young Readers

At the core, engaging young readers demands characters that are instantly appealing. Whizzy Studios emphasizes simplicity, expressiveness, and empathy to craft characters that aren’t just cute, but memorable and emotionally rich.

Authors, editors, and sometimes children test designs to ensure they support mood, message, and engagement—emphasizing character consistency and emotional resonance.
