On Colour Ramps and City Dashboards

Here are the colour ramps I am using for numeric measures in the recently launched CityDashboard (which by the way now has a new URL – http://citydashboard.org/): The colours have been designed to be clearly distinguishable from the white text that is on top of them. Here is the PHP code that I’m using to […]
