It says no 'No module named dist_info' when pip install
And it gives same error info in running "python setup.py install".

my python is 2.7.14, and this version of python is in the support list.

r, g, b = (0.9999999999999999, 0.9999999999999999, 1.0)

It would be very nice if Color objects had equality operator support. Defining __eq__ and __ne__ methods in Color class would suffice:

def __eq__(self, other):
    return self.hex == other.hex

def __ne__(self, other):
    return self.hex != other.hex

This would allow the following syntax to evaluate as True:

Color('white') == Color('white')

Gitchangelog is only needed for the developers of this package. Regular user who only use this package as a library don't need it as a dependency.

I just wanted to say thank you for working on things like this. Your color range list function was a lifesaver for me.
I did have a problem once in a while with matplotlib where it wouldn't recognize a non-normalized web hex format. For example, a value in the middle of a range landed on #393. Matplotlib wouldn't take this value as it apparently needed the normalized #339933. I used the webcolors package to normalize the output of my color range lists from colour to avoid the random problem of landing on a color value that didn't need all 6 digits to represent it. Before webcolors I tried formatting the color value using "%s"% and .hex but it remained a 3 digit color value that matplotlib wouldn't take. The piece of code they use to normalize is this:
if len(hex_digits) == 3:
hex_digits = u''.join(2 * s for s in hex_digits)

If I'm going about this reporting wrong maybe you can let me know what I should be doing differently. I'm new to open source projects like this. Thanks.

Nice job with this library.

The only thing I think is that it does not implement all the colour representations. Here's a check-list to motivate you to add those.

• Web (Hex/Colour Names)
• RGB
• CIELAB (LAB)
• HCL / LCH
• HSL
• HSV
• XYZ
• CYM
• CYMK

Possibly the best part of this library is that it is independent (single-file, no dependencies). I request you to please keep it the same.

When building a gradient from a color to black, the gradient go through many other hues, instead of going simply darker. It looks quite unnatural.
Wouldn't it be possible to treat white and black as special cases ?

Any idea on how to solve this? I'm not a Python expert and this seems to be a package related issue, instead of a distribution issue.

name colors does not work for all of them, thanks I wrote some tests before implement this library.

Right after doing a pip install colour I get this error when I try to call the Color constructor. I think you may have a bug in your setup.py file.

There is a collision in package name, both have package name == colour
This package and https://www.colour-science.org/installation-guide/

If the latter is installed in the PYTHONPATH, all attempts to import from colour import Color will fail.

Throws Traceback error, than only one color requested
list(Color("black").range_to(Color('white'),1))

ZeroDivisionError: float division by zero

Expected list with one element:
[<Color black>,]

In setup it is stated that this package is GPL and BSD licensed. Which one is it? Would it be possible to make this wonderful package BSD licensed?

Should be replaced with using setuptools directly. See the migration guide here:

https://github.com/embray/d2to1

Is it possible to make mutable properties like .luminance chainable like in spectra? (https://github.com/jsvine/spectra#colorbrightenamount10)

I can not import the most basic class and that is Color

from colour import Color
Traceback (most recent call last):
File "", line 1, in
ImportError: cannot import name 'Color' from 'colour' (unknown location)

this is in python3, and I am trying to run manim python code. How can I fix this?

Hi,

I searched in code, doc and issues but i didn't find a clear way to use CSS rgb values since Color rgb argument required float values.

Like for red color i have this CSS rule:
rgb(255, 0, 0)

I attempted to be able to do:

Color(rgb=(255, 0, 0))

Did i missed some helper or easy math to perform this ?

Thanks.

Is there a one-liner that I can use to get the color of a numeric value? For example, I want to make a color range from blue to red using 256 levels, where blue somehow maps to 0.0 and red maps to 1.0. From the markdown file I've come up with the following workflow.

from colour import Color
import numpy as np

# make the base colors
red = Color("red")
blue = Color("blue")

# define the color range
levels = 256
r_to_b = list(red.range_to(blue, levels))

def map(x, color_range, m=0.0, M=1.0):
    """ This map converts a numeric value to Color object in a list of Color objects """
    n = len(color_range)
    numeric_range = np.linspace(m,M,n)
    nearest_idx = np.abs(x - numeric_range).argmin()
    return color_range[nearest_idx]

# retrieve the color of float x
x = 0.2425
color_x = map(x, r_to_b)

Is this functionality already present in colour, or do you see a better implementation?

I might be totally off base here, but i think you're conflating lightness and luminance?

HSL is hue, saturation, lightness

luminance is sqrt( 0.299R^2 + 0.587G^2 + 0.114*B^2 )

It pip install fails, as it can't find the CHANGELOG.rst file

Pypi shows BSD-3-Clause, LICENSE and github show BSD-2-Clause.

At the moment I have to wrap it like this

c = colour.hex2rgb(colour.web2hex(args))

There's no linear interpolation .. is that correct?

Context.. see https://www.vis4.net/blog/2011/12/avoid-equidistant-hsv-colors/
or https://www.alanzucconi.com/2016/01/06/colour-interpolation/

Hello, when i use

oldcolor = Color('#800080')
newcolor = Color('#000080')
oldcolor.range_to(newcolor, 100)

the list goes through the whole rainbow (red, yellow, etc).
An option for a range with a shortest path, kind of a CMYK way, transitioning trough mauve or lilac to blue would be nice.

plt.show()

How can I use colour package in order to create a custom gradient and use it with matplotlib? I tried to create a gradient from brown to green in this way:

from colour import Color
brown = Color("brown")
cl = list(brown.range_to(Color("green"),3))

But it gave me error when plugging cl to the code I've given above..

Thanks for this library, it's very cool and useful. Maybe you could add another kind of range in order to make gradients, e.g. now the color range from blue to white is "passing" through other colors, like green, while it would be nice to have also the opportunity to make a gradient from blue to white which is just making the blue paler and paler until white, so basically it would be a lightness based range.

Hello, I am trying to install colour in Slackware 15 Beta 1 and I am getting this error when I run ./autogen.sh.

autogen.sh: error: Didn't find a git repository (or no tags found). ``./autogen.sh`` uses git to create changelog and version information.

As I understand it autogen.sh should create a Changelog.rst file needed by setup.py. However I need to get past the above error. Any help with this is appreciated.

Thank You.

Because of the following reasons, this package is not install-able from git:

• %%version%% is in setup.py
• CHANGELOG.rst does not exist in the repository and setup.py depends on it.

Currently, All attributes and methods of Color return tuples or strings. It should be relatively simple to return namedtuples instead of simple tuples.

Why?
Namedtuple makes your tuples _self-document. You can easily understand what is going on by having a quick glance at your code._¹

Is HSV going to be supported? The readme says it is supported, but I found only HSL implemented.

Thank you.

Hi!

This is a friendly notice to let you know that Debian is working on packaging your software for Debian. You can follow the progress of that work in bug #867800 in the Debian Bug Tracking System (BTS).

The source code for the Debian package is in this git repository. It will be uploaded into Debian shortly, at which point it will end up in the NEW queue for legal review. Once the NEW process is completed, it takes about 10 days for the package to trickle down into "testing", which will become the next Debian release. This means your software will eventually be shipped in a "long term support" release, which last from three to five years, according to the current statistics.

If you are interested in maintaining the package yourself upstream, that is definitely possible. You can either upload the package yourself if you are a Debian member or I can act as a sponsor when a new release is published.

This is just a notification, but can also act as a coordination point for upstream packaging if you wish to followup on this. otherwise, feel free to close this issue whenever you like.

Is there a chance integer RGB values can be accepted? It makes compatibility with PIL's color signatures more streamlined.

Trying to generate a Colour object using 0, 255, 0 RGB value and read back the rgb tuple. Getting a exponential negative value in place of blue.

Also tried,

Color("lime").rgb
Color("#00FF00").rgb
Color(rgb=(0,1,0)).rgb

CSS spec defined an RGBA color specification: https://www.w3.org/wiki/CSS3/Color/RGBA

However, passing a value like 'rgba(0, 0, 0, 1)' results an the error:

ValueError: 'rgba(0,0,0,1)' is not a recognized color.

This makes storing values that are intended for use in stylesheets impossible without doing unnecessary conversion.
