colors.py

Convert colors between rgb, hsv, and hex, perform arithmetic, blend modes, and generate random colors within boundaries

Installation

$ pip install colors.py

Basic Uses

Importing

>>> from colors import rgb, hsv, hex, random

Create an RGB color object

>>> rgb(100, 100, 100)

Convert it to hexadecimal

>>> rgb(100, 100, 100).hex

Coerce the hexadecimal to a normal string

>>> str(rgb(100, 100, 100).hex)
646464

Create a Hexadecimal color object

>>> hex('646464')

Extract the red/green/blue value from a hexadecimal

>>> hex('646464').rgb.red
100

Convert a hexadecimal to HSV

>>> hex('646464').hsv

Coerce hsv/rgb values to a list/tuple of values

>>> list(hex('646464').hsv)
[0.0, 0.0, 0.39215686274509803]

Create an HSV color object

>>> hsv(0, 1, 1)

Convert it to RGB

>>> hsv(0, 1, 1).rgb

Gimme a random color, any color!

>>> random()

Coerce a hexadecimal color to a string with formatting

>>> '#%s' % random().hex
'#2f2336'

Coerce RGB/HSV objects to a string for formatting

>>> 'style="color: rgb(%s)"' % random().rgb
'style="color: rgb(80.3414147839, 124.403236079, 71.4620739603)"'

Compare color equality

>>> rgb(100, 100, 100) == hex('646464')
True
>>> hsv(0, 1, 1) == rgb(255, 0, 0)
True

Arithmetic

Note: All arithmetic operations return

rgb

Multiply

>>> hex('ff9999') * hex('cccccc')

>>> _.hex

>>> rgb(100, 100, 100).multiply(hsv(0, 1, 1)).hex
>>> 

Add

>>> hex('ff9999') + rgb(10, 10, 10)

>>> hex('aaffcc').add(rgb(10, 10, 10))

Subtract

>>> hex('ff9999') - rgb(10, 10, 10)

>>> hex('aaffcc').subtract(rgb(10, 10, 10))

Divide

>>> hex('ff9999') / rgb(10, 10, 10)

>>> hex('aaffcc').divide(rgb(10, 10, 10))

>>> rgb(100, 100, 100) / hex('00ffff')

Blend Modes

Note: All blend modes return

rgb

Screen

>>> hex('ff9999').screen(rgb(10, 10, 10)).hex

Difference

>>> hex('ff9999').difference(rgb(10, 10, 10)).hex

Overlay

>>> hex('ff9999').overlay(rgb(10, 10, 10)).hex

Invert

>>> hex('000000').invert()

The Color Wheel!

The color wheel allows you to randomly choose colors while keeping the colors relatively evenly distributed. Think generating random colors without pooling in one hue, e.g., not 50 green, and 1 red. ```python

from colors import ColorWheel wheel = ColorWheel() ```

Iterate the wheel to get the next value

ColorWheel is an iterable, but be careful if using inside any type of loop. It will iterate forever until you interject. ```python wheel.next() wheel.next() for color in wheel: ... print color.hex 00cca4 002ecc

Forever and ever and ever and ever
