Top Undertale And Deltarune Coloring Tips & Craft Ideas
Coloring these characters is a fantastic way to express your fandom and explore the unique pixel-art-inspired aesthetic of both games. Because Undertale and Deltarune rely heavily on bold shapes and expressive line art, these pages are well-suited to a range of tools — from simple colored pencils to vibrant alcohol markers.
- Dark World vs. Light World: Use neon and highly saturated colors for Dark World characters like Susie and Ralsei, and softer, more muted tones for Light World scenes to reflect each setting’s atmosphere.
- Skeleton Shading: For Sans and Papyrus, use metallic grey or silver pencils for armor details and a light blue wash on Sans’s hoodie — leaving the bone-white areas completely uncolored for authenticity.
- Pixel-Style Technique: Experiment with small, square-shaped strokes to mimic the original pixel art aesthetic of the games — a fun challenge that brings a retro-game feel to the finished page.
- Flowey’s Expression: Take creative liberty with Flowey! Color him in his innocent yellow form for early-game vibes, or use red accents and dark shading to reflect his true Omega Flowey nature.
- DIY Bookmarks: Laminate your smaller finished pages and cut them into strips for custom Undertale bookmarks — great for gifts or for fellow fans of the series.
- Crossover Collage: Print both Frisk and Kris pages and display them side-by-side for a stunning dual-game tribute that highlights how Toby Fox’s creative vision evolved across both titles.
Don’t be afraid to mix and match characters from both games! Since the universes share themes and design DNA, creating scenes that blend Undertale and Deltarune characters makes for imaginative fan art. Whether you are coloring for fun, mindfulness, or as a gift for a fellow fan — we hope these pages bring you as much joy as the games themselves.
