Try another version of the bright reflection

Original creative challenge · The honest caption

1. Use this invented starting situation: A reflected patch of colour looks like a separate object.
2. Check the wider image before naming what the reflection is.
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.
