Section 01 / 10 — Systematic Grid

The Complete Palette

All 128 colors arranged in their original TIA register order — 16 hue families along rows, 8 luminance steps across columns. Each swatch is a specific voltage-timed chroma burst encoded into the NTSC signal.

Section 02 / 10 — Spectral Wave

Luminance Oscillations

Colors plotted as a continuous waveform, each hue family rendered as an animated oscillation. The amplitude represents perceived brightness (luma); frequency encodes hue angle on the NTSC color subcarrier.

Section 03 / 10 — Polar Chromatic Map

The Hue Wheel

Plotted in polar coordinates: angular position encodes hue register (0–360°), radial distance encodes luminance. Hover or tap any swatch to inspect its chromatic coordinates.

Section 04 / 10 — Luma Rivers

Rivers of Light

Each hue family flows as a horizontal river from its darkest register value (luma 0, left) to its brightest (luma 7, right). The height of each river encodes relative perceptual luminance using the NTSC luma formula: Y = 0.299R + 0.587G + 0.114B.

Section 05 / 10 — Generative Pixel Art

The Pixel Canvas

Algorithmic pixel art generated exclusively from Atari 2600 palette colors. Each pattern is computed using mathematical functions — Perlin-like noise, sine interference, Voronoi tessellation — translated to the nearest available TIA register color.

Section 06 / 10 — RGB Color Space

Colors in Three Dimensions

The 128 palette colors mapped into the RGB cube. Each point's X, Y, Z position corresponds directly to its Red, Green, Blue channel values. Drag to rotate. The structure reveals how NTSC encoding distributes colors non-uniformly through RGB space.

Section 07 / 10 — Chromatic Frequency

Frequency Spectrum

Each of the 128 colors visualized as a vertical bar, height proportional to perceived luminance. Colors are sorted by hue angle then luminance, creating a continuous chromatic frequency spectrum analogous to a visible-light spectral diagram.

Section 08 / 10 — Technical Data Matrix

The Data Matrix

Complete technical readout: all 128 colors with hex codes, RGB decomposition values, and perceptual luma. A direct interface with the palette as raw data — the way a programmer in 1979 would have seen it in the TIA register documentation.

Section 09 / 10 — Generative Art Engine

Algorithmic Paintings

Mathematical beauty rendered exclusively with Atari palette colors. Flow fields, strange attractors, recursive geometry — each click generates a unique composition. Art made entirely from 128 colors and pure mathematics.

Section 10 / 10 — Spectral Analysis Cards

Color Spectra

Each hue family as a spectral analysis card: dominant swatch, RGB channel breakdown bars, hexadecimal readout, and perceptual luma coefficient. Sixteen complete chromatic profiles — the full scientific identity of every Atari hue family.
