# Fractal Flame × Reaction–Diffusion — composed image prompt

# Fractal Flame carries the structure and Reaction–Diffusion appears as the accent.
# Style descriptors only. This prompt names no artist, studio, brand or work.

Produce four original images that take their structure from Fractal Flame (technique, 1992–) and their accent from Reaction–Diffusion (technique, 1952–).

## What to make

Make the kind of thing Fractal Flame exists for: generating organic high-density stills and motion from mathematical iteration, or creating luminous structures for music or exhibition imagery that retain detail when enlarged. Choose one subject and hold it across all four.

## Structure comes from Fractal Flame

- Translucent branching like flame or feathers
- Bright high-density regions emerging from darkness
- Self-similar detail continuing under magnification
- Smooth color driven by transformation history

Composition: Grow branches from one dense core and preserve a dark resting field around them. Type and lettering: Keep copy outside the generated field or anchored in dark regions.

## Accent comes from Reaction–Diffusion, used sparingly

- Round spots dividing at even distances
- Continuous curving maze stripes
- Coral or cellular boundaries branching from edges
- Self-organized marks of nearly constant thickness

Let one material quality come from it: Set reaction terms, diffusion rates, feed and kill rates, then iterate from a small perturbation.

## Colour and feeling

Build the ground on #57D8D0, carry the structure in #F05A9D and #080713, and let a single accent come from #38C6A3. These are read off real works, so a direction rather than a fixed palette.
Feeling to carry: futurity, exhilaration, technique.

## Where they fight

- Fractal Flame and Reaction–Diffusion both belong to Computational Expression, so the difference is small. Push the roles further apart than feels comfortable.
- Fractal Flame and Reaction–Diffusion are techniques rather than looks. Decide which one runs last in the process, because that is the one that will show.

## What goes wrong

- Fractal Flame: A rainbow spiral fractal is not a Flame. Preserve nonlinear variation, density display and structural color.
- Reaction–Diffusion: A hand-drawn animal print is not reaction-diffusion. Time and parameter changes must remain visible in the pattern.

## Across the four

Keep the roles fixed in all four. Vary the framing, the scale and the arrangement so the set shows what this pairing can do rather than four versions of one picture.

## Constraints

- Do not imitate, reference or name any specific artist, studio, brand, character or copyrighted work.
- Do not reproduce the composition of an existing work.
- Produce original compositions in the general period languages described above.
