Complex / 2d colormap

Installation

Install this via pip (or your favourite package manager):

pip install colormap-complex

Usage

from colormap_complex import colormap
import numpy as np

lin = np.linspace(-1, 1, 100)
x, y = np.meshgrid(lin, lin)
z = x + 1j * y
c = colormap(type="oklab")(z.real, z.imag, scale=True)
plt.imshow(c, extent=(-1, 1, -1, 1), origin='lower')

All colormaps

Examples

Description

• "bremm", "cubediagonal", "schumann", "steiger", "teulingfig2", "ziegler" colormaps are collected from spinthil/pycolormap-2d which is based on:

  M. Steiger, J. Bernard, S. Thum, S. Mittelstädt, M. Hutter, D. A. Keim, and J. Kohlhammer, “Explorative Analysis of 2D Color Maps,” in International Conferences in Central Europe on Computer Graphics, Visualization and Computer Vision, 2015, vol. 23, pp. 151–160.

• Other colormaps are built on top of colour-science/colour and created by the author.
• "oklab", "prolab" are perceptually uniform (lightness) colormaps.
• "oklch", "prolch" are perceptually uniform (chroma) colormaps. X axis corresponds to Hue and Y axis to Lightness.
