European Geosciences Union (EGU) Colours

European Geosciences Union (EGU) colour palettes and division colours derived from EGU’s visual identity and structure overview. The package can be installed via pip:

python -m pip install egucolours

Separate sub-modules for the main palette, neutral palette, and division colors are available. Each module contains a dict-like collection colours which holds all colours of the respective palette. The colours are compatible with the matplotlib colour mechanics and can be used in the same fashion as hex-strings or RGB triples.

>>> import matplotlib.pyplot as plt
>>> import egucolours

>>> plt.plot(x, y, color=egucolours.division.AS)

Colours can be accessed by their name. For the main palette, this looks like as follows:

>>> import egucolours
>>> print(egucolours.main.colours)
{'blue': '#0072bc', 'yellow': '#ffde00'}

>>> print(egucolours.main.blue)
EGU blue:      RGB   0 | 114 | 188      (#0072bc)

>>> print(egucolours.main.colours['blue'])
EGU yellow:    RGB 255 | 222 |   0      (#ffde00)

Division colours can be accessed in a similar fashion:

>>> import egucolours
>>> print(egucolours.division.AS)
EGU AS:        RGB  66 |  66 | 212      (#4242d4)

>>> print(egucolours.division.colours['AS'])
EGU AS:        RGB  66 |  66 | 212      (#4242d4)

The egucolours package contains a top-level dict-like collection with all palettes:

>>> import egucolours
>>> print(egucolours.colours)
{'blue': '#0072bc', 'yellow': '#ffde00', 'white': '#ffffff', 'grey': '#a8a9ad', 'AS': '#4242d4',
'BG': '#1a4d04', 'CL': '#5f3172', 'CR': '#007db8', 'EMRP': '#87251f', 'ERE': '#2a6736',

Classes

class egucolours.Colour(name, hex_value)[source]

Class representation of a colour.

The colour is instantiated by its hex value, i.e. Colour(name, hex_value). This class is designed to be compatible with the matplotlib colour mechanics, but holds additional metadata in the form of the colour name.

Parameters:

  • name (str) – Colour name

  • hex_value (str) – Hexadecimal representation of the colour (e.g., “#ffffff”)

property RGB

RGB representation of colour

Returns:

RGB triple (e.g. (255, 255, 255))

Return type:

tuple of int

property hex

HEX representation of colour

Returns:

Colour hex string (e.g. #ffffff)

Return type:

str

property name

Colour name

Returns:

Colour name

Return type:

str

property rgb

rgb representation of colour

Returns:

rgb triple (e.g. (1.0, 1.0, 1.0))

Return type:

tuple of float

class egucolours.ColourMapping(colour_dict)[source]

Class representation of a colour dictionary. The key/value pairs cannot be altered after instantiation.

Parameters:

colour_dict (dict) – dictionary of name: hex_value pairs
