# Style descriptors only. This prompt names no artist, studio, brand or work.

Produce four original images in the visual language of Goryeo Celadon, a style from Ceramic Styles, 918–1392.

## What to make

Make the kind of thing this style exists for: fixing the green range as a colour reference for an exhibition or catalogue of Korean ceramics, or translating the look of pattern sunk beneath a translucent layer into print finishing or screen layers. Choose one subject and hold it across all four images.

## What has to be visible

- A translucent glaze running from green to bluish over a grayish white body
- Inlaid lines of white and red slip sitting visibly below the glaze surface
- Incising, relief carving and openwork used together on one vessel
- Small passages of iron or copper pigment painting, dark brown or red, on the green ground

Someone who knows this style should be able to point at each of these in the finished image.

## How to build it

- Layout and structure: Run narrow bands at the rim and foot and leave the wide body largely open. Scatter motifs on a diagonal rather than symmetrically so the void carries the piece
- Type and lettering: The vessel itself carries almost no lettering. If a mark or a label is needed, set it small in a fine serif with thin vertical strokes, clear of the ornament's empty ground
- Material and surface: Cover a grayish white body carrying trace iron with a translucent glaze between green and blue green. Cut the pattern into the body, fill it with white and red slip, then glaze over so it sinks
- Colour: #D9D2BE carries the ground, #7E9A86 is the colour the style is remembered by, #3B3730 holds text and outlines. Read off real works, so treat them as a direction rather than a fixed palette.
- What it should feel like: calm, luxury, technique

## What goes wrong

Flattening bisaek into a generic green makes the inlay read as printed on the surface and destroys the depth the style depends on.

## Across the four

Keep every cue above present in all four. Vary the framing, the scale and the arrangement so the set shows the range this style covers 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 language described above.
