Produce four original images in the visual language of Chinese Blue-and-White Porcelain, a style from Ceramic Styles, 14th century–.

## What to make

Make the kind of thing this style exists for: building tone in a one colour print by splitting the drawing into a dark outline pass and a pale wash pass, or making white read as figure rather than background by flooding the ground and reserving the letterforms. Choose one subject and hold it across all four images.

## What has to be visible

- One blue on a white porcelain ground, with no second colour anywhere
- A dark outline drawn first, then filled with paler washes that grade like ink painting
- Motifs reserved in white against a densely painted blue ground
- The painting sits under the glaze, so the surface stays smooth and no brushstroke stands proud

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: Divide the curved wall into bands at rim, body and foot, and vary density band by band. Leave a wide white margin around the main motif on the body
- Type and lettering: Set any inscription in the same blue and the same brush weight as the painting, never in an even mechanical line
- Material and surface: A white body and cobalt oxide alone. Build two values, a dark drawn line and a pale wash, and lift motifs out of a flooded blue ground in reserve. All of it goes under a clear glaze and fires once
- Colour: #F4F1E8 carries the ground, #6E8FC0 is the colour the style is remembered by, #1E3A76 holds text and outlines. Read off real works, so treat them as a direction rather than a fixed palette.
- What it should feel like: technique, luxury, calm

## What goes wrong

Treating the blue as one flat tone and skipping the graded washes turns the drawing into a printed screen tint and erases the brush.

## 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.
