Complex / 2d colormap

## Installation

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

```shell
pip install colormap-complex
```

## Usage

```python
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", scale=True)(z.real, z.imag)
plt.imshow(c, extent=(-1, 1, -1, 1), origin='lower')
```

### All colormaps

### Examples

![z^(2/3+i)](https://raw.githubusercontent.com/34j/colormap-complex/main/complex-function-z-2-3-i-cyl.jpg)

### Description

- `"bremm", "cubediagonal", "schumann", "steiger", "teulingfig2", "ziegler"` colormaps are collected from [spinthil/pycolormap-2d](https://github.com/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](https://github.com/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.
