What is an AllRGB Image?

An AllRGB image is a picture that contains every possible color in the RGB spectrum exactly once. For example, an 18-bit AllRGB image contains exactly 262,144 unique pixels, each representing a unique color from the 18-bit color space.

  • Unique Colors: Every pixel is mathematically unique.
  • Artistic Conversion: Your uploaded images are used as a reference to organize the colors, creating a unique mosaic effect.
  • Hilbert Curve Mapping: Uses advanced space-filling curves to maintain image structure while strictly adhering to the unique color constraint.
