100 Color by Number Mysteries: A Coloring Book for Adults Relaxation and Wonder Squares, Diamonds, Dots (Pixelcolorist Quest) is a large, high-quality adult coloring book designed for stress relief, focus, and creative satisfaction. Published in early 2025, it belongs to the popular “Pixelcolorist Quest” series and offers exactly what the title promises: 100 intricate color-by-number puzzles in three different grid styles.

What’s Inside

  • 100 unique color-by-number pages divided into three categories:
    • Squares (standard grid style)
    • Diamonds (rotated or diamond-shaped grids for added visual interest)
    • Dots (dot-based designs that create a softer, more artistic look when completed)
  • Mystery images — Each page starts as a numbered grid. As you color according to the number key, a beautiful hidden picture gradually appears. You won’t know exactly what you’re creating until it’s nearly finished, which adds an element of surprise and wonder.
  • Themes — The designs feature a wide variety of relaxing and wondrous subjects: mystical forests, intricate mandalas, peaceful landscapes, fantasy scenes, animals, flowers, celestial patterns, and abstract geometric art.
  • Color key — Each page includes a clear, easy-to-follow color palette (usually 20–30 colors). The numbers correspond to specific shades, so even beginners can achieve beautiful, consistent results.
  • Paper quality — Single-sided, thick, premium paper that works well with colored pencils, gel pens, and markers (with minimal bleed-through when using pencils or fine-tipped markers).
  • Size — Standard adult coloring book size (approximately 8.5″ × 11″), easy to use on a table or lap.

Why Adults Love It

  • Relaxation + gentle challenge — The number-following aspect keeps your mind quietly engaged while the coloring process is soothing and meditative.
  • Surprise element — Not knowing the final image until you’re halfway through makes each page feel like opening a present.
  • No decision fatigue — You don’t have to choose colors or worry about “getting it right.” Just follow the numbers and enjoy the process.
  • Beautiful finished results — Even first-time colorists end up with professional-looking artwork they can frame or gift.
  • Great for gifting — Popular as a birthday, holiday, get-well, or “thinking of you” present for anyone who enjoys coloring for relaxation.

Best For

  • Adults seeking a calming, low-pressure creative hobby
  • Beginners who want structure but still want pretty results
  • Anyone who loves mystery pictures, pixel art aesthetics, or numbered coloring books
  • People who find traditional coloring books overwhelming due to color choice

Minor Notes

  • Best results with colored pencils or fine-tipped markers (heavy markers may bleed through to the next page).
  • The book is quite thick, so it lies flat nicely but can be heavy to hold for long periods.
In short, 100 Color by Number Mysteries is a wonderful choice if you want a large collection of relaxing, surprise-filled coloring pages that feel both creative and structured. It’s especially satisfying for anyone who enjoys the “reveal” aspect of color-by-number and wants a long-lasting book to return to again and again.
