Try another version of the one-colour scene

Original creative challenge · Originality through constraints

1. Use this invented starting situation: A drawing relies on many colours to separate objects.
2. Try one colour and use spacing or line weight to create distinction.
3. Make a small artefact that shows the change: a note, sketch, caption, or three-panel sequence.
4. Write one sentence describing what the artefact makes clearer. Keep this an experiment; no account, purchase, or public post is needed.
