zuericolors

zuericolors is an R-Package, which provides specific colors according to the corporate design of the city of Zurich. The package contains all colors that Statistik Stadt Zürich needs for the creation of graphs. There are two main functions in zuericolors:

• get_zuericolors extracts colors of a specific color palette and puts them into a vector.
• view_zuericolors prints a specific color palette. Is useful for visual inspection.

For the creation of CI/CD conform ggplot2 graphs see the zueritheme and zueriplots repositories.

Usage

Grey Palette

The grey color palette is not a palette in the true sense. However, its individual colors are needed for different features in sszviz:

• LightGry #FAFAFA: A light grey scale is included for use in cases where a data background should be shaded out.
• PaleGry #EAEAEA: A pale grey shade which is used for elements which should be in the background, but shouldn’t completely fade out. Currently used as the color of the links in the sankey diagram.
• Gry #D6D6D6: A grey scale is included for use in cases where a data value should be shaded out. Currently, it is used for the color of inactive lines in the coordinated map and line chart example. At the moment, it has only one value.
• DimGry #B8B8B8: A dim grey shade used for highlighting elements which are normally grey (sszvis.scaleGry()). Currently, it is used as the highlight color in the bubble map.
• MedGry #7C7C7C: The medium grey color, as a standalone value.
• DeepGry #545454: The deep grey color, as a standalone value.

Qualitative Palettes

Qualitative palettes are used for data that has distinct categories. They distinguish categories based on color contrast. They should never be used to compare values, use sequential or divergent palettes in this case.

Sequential Palettes

Sequential palettes are used to compare values. These palettes are designed to have the same brightness for the same input value.

Divergent Palettes

Divergent palettes are used to compare data that has two extremes. These scales are designed to have the same brightness for the same input value. They come in two color variations: the valued (red-green) variation is used for data that has negative-positive characteristics, the neutral (brown-blue) variation is used in cases where no valuation is wanted.

Palettes for Gender and Origin

#DB247D is used for women, #3431DE for men. The grey #7C7C7C for plotting total values (female and male combined). #FB737E is used for female foreigners, #0A8DF6 for male foreigners.
