Colour whole areas or smaller districts

A map can contain a broad boundary layer and a more detailed one. The Colour: control tells you which level a click will affect. The Detail: control describes the map product itself.

   Colour: choose the boundary level

   Click Colour: to choose which boundary level a click will affect. On UK postcode district or sector maps, zooming also changes the automatic mode between broad and detailed boundaries. On US state maps, your choice stays fixed while you zoom: choose States for a whole state, or Counties / ZIP codes for individual areas. Always read this label before coloring.

2. 2

   The whole-area warning

   If smaller areas already have a mixture of territory colors and you try to color their whole parent area or state, the tool warns you before replacing that work. Choose Keep existing colours to leave it alone, or Colour whole area / Colour whole state to replace the assignments. On UK maps this can also happen after zooming changes the automatic mode.

3. 3

   After replacing a whole area

   If you confirmed a replacement by mistake, use Undo straight away to restore the previous colors. To build a mixed territory, switch back to the smaller boundary level and color the individual districts, sectors, ZIP areas or counties instead.

   Detail: see or choose another map

   Opens a short explanation of the current boundary detail and a suggested more detailed map, where one exists. The preview/browse link opens another map choice; it is not a switch that adds new geometry to your current saved artwork. Save your current work before leaving.
