The map of voting in the 1987 British general election (Colour).

Three colours are mixed for the three major parties in each of 633 mainland parliamentary constituencies on an equal land area map software by author on an Archimedes computer.

The map is annotated by the (occasionally obscured) full names of constituencies. It shows a very different picture to the cartogram (Plate LXXI). England is covered by the blues, greens and purples that spell out a Conservative landslide; while the yellow and lime greens of Scotland and Wales show us Liberal country. The red of the Labour party is relegated to a few cities, only really visible in the Scottish, North-East, Welsh and Yorkshire coalfields. The map is deceptive, the population cartogram actually giving the true spatial balance of the votes.
