Most "coloring books" are AI sludge — random lines, zero thought.

This one’s different.

At Riku Aki, every page is hand-designed to help you color like a pro, not just pass time.

✅ 350 Color Swatches – Test every shade before ruining your next masterpiece
✅ 40 Color Palettes – Organize your tones like a trained artist
✅ Color Wheel + Harmony Diagrams – Finally get why some combos slap (and others flop)
✅ 80 Blending Spaces – Level up your fades, transitions & gradient flex
✅ 20 Shadow Zones – No more flat-looking art
✅ 20 Highlight Zones – Make your colors pop with depth
✅ 20 Practice Patterns – For skill drills (or lazy color-and-chill days)
✅ 20 Pre-Made Objects – Shade, blend, and show off on Insta
✅ 100 Free Spaces – For wild ideas, midnight experiments, or full chaos mode

This isn’t just a coloring book.
It’s your training ground.
