## SecretColors

[![PyPI version](https://badge.fury.io/py/SecretColors.svg)](https://badge.fury.io/py/SecretColors) [![Documentation Status](https://readthedocs.org/projects/secretcolors/badge/?version=latest)](https://secretcolors.readthedocs.io/en/latest/?badge=latest)

Library generated for making plots with better color palette. It uses  famous color palettes and adds few helpful functions.

Currently it supports following Color Palettes

- IBM Color Palette (`ibm`)
- Google Material Design Color Palette (`material`)
- Google Material Design Accent Color Palette (`material-accent`)
- ColorBrewer2 Color Palette (`brewer`)
- VMWare Clarity Color Palette  (`clarity`)
- Tableau Color Palette (`tableau`)

You can get output of colors in variety of color formats including `hex` , `rgb`, `rgba` etc.

See [changelog](/CHANGELOG.md) to know what's new!

Few sample plots and inspiration behind this library can be found in [WeirdData blog](https://weirddata.github.io/2019/06/11/secret-colors-2.html).

### Installation

pip install SecretColors

### Documentation

Full documentation and API reference can be accessed via [ReadTheDocs](https://secretcolors.readthedocs.io)

**SecretColors** is a very flexible library. You can easily select different color palettes.

from SecretColors import Palette
    
    p = Palette()  # Generates Default color palette i.e. IBM Color Palette
    ibm = Palette("ibm")  # Generates IBM Palette
    ibm.red()  # Returns '#fb4b53'
    material = Palette("material")  # Generates Material Palette
    material.red()  # Returns '#f44336'

Select different types of color modes

p1 = Palette() # Default Color mode (hex)
    p1.green() # '#24a148'
    p2 = Palette(color_mode="hexa")
    p2.green() # '#24a148ff'
    p3 = Palette(color_mode="ahex")
    p3.green() # '#ff24a148'
    p4 = Palette(color_mode="rgb")
    p4.green() # (0.141, 0.631, 0.282)
    p5 = Palette(color_mode="rgba")
    p5.green() # '(0.141, 0.282, 0.631, 1)'

Note: `matplotlib` can accepts *hex*, *rgb* or *hexa*

Get random colors

p = Palette()
    p.random() # '#90dbe9'
    p.random(no_of_colors=3) # ['#8fca39', '#64a0fe', '#7430b6']
    p.random(no_of_colors=2, shade=20) # ['#b3e6ff', '#c2dbf4']

Unlimited color manipulations

p = Palette()
    p.blue()  # normal blue [#408bfc]
    p.blue(shade=20)  # lighter shade of blue [#c9deff]
    p.blue(shade=70)  # darker shade of blue [#054ada]
    p.blue(shade=16.10)  # arbitrary shade of blue (between 0 to 100) [#dbe9ff]
    p.blue(no_of_colors=3)  # Three blue shades ['#b8d4ff', '#408bfc', '#0546d4']
    p.blue(no_of_colors=3, starting_shade=30)  # Three blue shades with lightest one is 30 ['#64a0fe', '#005ef9', '#052ea8']
    p.blue(no_of_colors=3, ending_shade=40)  # Three blue shades with darkest one is 40 ['#edf4ff', '#c9deff', '#97c1ff']
    p.blue(no_of_colors=3, starting_shade=30, ending_shade=40) # Three blue shades with lightest 30 and darkest 60 ['#8cbaff', '#8cbaff', '#8cbaff']
    p.blue(no_of_colors=3, gradient=False) # Three blue shades in random order ['#8cbaff', '#b8d4ff', '#64a0fe']
    p.color_mode = "rgba"
    p.blue(alpha=0.3) # Blue with alpha (0.251, 0.988, 0.545, 0.3) Only works in color mode which outputs alpha values

Flexible functions

get_complementary("#24a148") # Get complementary color [#a0237c]
    hex_to_rgb("#a0237c") # (0.627, 0.137, 0.486)
    hex_to_hsl("#a0237c") # (0.881, 0.641, 0.382)
    hex_to_hex_a("#a0237c", alpha=0.7) # Get hex with transparency at end [#a0237cb2]
    hex_to_ahex("#a0237c", alpha=0.7) # Get hex with transparency at start [#b2a0237c]
    color_in_between("#24a148","#a0237c") # Color between two ['#616161']
    color_in_between("#24a148","#a0237c", steps=4) # 3 colors between two ['#428154', '#616161', '#80426e'] such that color space is divided into 4 parts
    rgb_to_hex(0.181, 0.241, 0.382) # '#2e3d61'
    rgb_to_hsl(0.181, 0.241, 0.382) # (0.617, 0.357, 0.281)
    hsl_to_hex(0.181, 0.241, 0.382) # '#747849'

Custom and flexible colormaps which can be directly used in `matplotlib` workflow

import matplotlib
    import matplotlib.pylab as plt
    import numpy as np
    from SecretColors.cmaps import ColorMap
    from SecretColors import Palette
    p = Palette()
    c = ColorMap(matplotlib, p)
    data = np.random.rand(100, 100)
    plt.pcolor(data, cmap=c.greens())
    plt.show()

Create your own colormaps or make it *qualitative* colormap

color_list = [p.red(), p.blue()]
    plt.pcolor(data, cmap=c.from_list(color_list, is_qualitative=True))
    plt.show()

Reverse the direction

plt.pcolor(data, cmap=c.greens(is_reversed=True))

### TODO
 - [ ] CIE XYZ to CIE Lab conversions
 - [ ] Color Palettes - Latitude, Polaris, Adobe Spectrum
 - [ ] Direct support for more RGB to XYZ conversions
 - [ ] Generate Color Palette from image
 - [x] Color blind safe palette
 - [ ] ~~Out of the box `LinearSegmentedColormap` object~~ 
 
 We can not implement 'out of the box' colormaps for matplotlib because `matplotlib` checks its
  `type` before its use. Hence we can not make new class which can be directly
   act as a substitute.

Note: All CIE-XYZ conversion and colorblind simulation functions are still in
 beta-testing. Do not use them in your production code
