Fill
A method of containment that assigns colors to borders and shapes
Why it matters
The heaviest grouping tool after borders: a filled surface says “this is one thing” before any label does. Fills also carry state — hover, selected, disabled — which is why a fill change with no meaning behind it confuses.
