An inked character in flat paint, laid over a painted background that is made a different way.

What it is for

A drawn figure reads as a character and a painted background reads as a place. Holding them apart is what lets a viewer accept a line drawing standing in a real wood, and it is the oldest trick the medium has.

How it works

The character is inked on a clear sheet and painted from behind, so the colour is flat and the line stays clean on top. The background is painted once, on paper, with no outline anywhere. The two are photographed together, which is why the figure always sits a fraction proud of the place it is in.

When to use it

Use it when the character has to carry the frame and the setting has to stay quiet behind it. It is the wrong choice when the scene itself is the subject, because a figure drawn this way will always pull the eye first.

Told apart from its neighbours

Anime Cel shares the flat paint but cuts the shadow into a hard graphic shape and thins the line. Ligne Claire drops the shadow altogether and outlines the background too. Cartoon Modern keeps the flat paint and throws away the roundness.

Where it is used

It is the default look for anything that wants to read as classic animation without naming a studio, and it carries a picture book, a title card and a music video equally well.

The prompt

Replace the blanks with your own character, keep the rest. Then run it on an image model.

<character>, cel animation style, a crisp black ink outline of even weight around the figure, flat opaque paint inside it in two tones only, a hard shadow shape rather than a gradient, the background painted in soft gouache with visible brushwork and no outline at all, the figure sitting slightly separate from it

Run it

What goes wrong

The usual failure is one flat world: the model outlines the background, and the figure stops standing out. The fix is a clause about the background alone, saying painted, soft and unoutlined.

Leave out

gradients on the character, a painted outline on the background, airbrush shading, photoreal texture, a sketchy line

Watch for

The whole look lives in the difference between the two layers. Ask for the background to be painted and unoutlined in the same sentence that asks for a hard line on the figure, or a model renders both the same way and the depth goes.

Questions

Both use flat paint under an ink line. Anime cuts the shadow into a hard graphic shape, uses a thinner line, and often blows the highlight out to white. Classic cel keeps the shadow soft in shape and the line even in weight.
