Getting dominant color of an image

Question

How can I get the dominant color of an image as rgb or hexcode?

I found a script called Color Thief but it does not allow image URLs only paths.

Color Thief uses jQuery, but if there’s another solution (PHP or whatever) I’d love to use that instead. — user1706680, Dec 11 '12 at 00:09

use urllib to download the image first, then delete the unnecessary file:

from colorthief import ColorThief
import urllib
import os
def dominant_color_from_url(url,tmp_file='tmp.jpg'):
    '''Downloads ths image file and analyzes the dominant color'''
    urllib.urlretrieve(url, tmp_file)
    color_thief = ColorThief(tmp_file)
    dominant_color = color_thief.get_color(quality=1)
    os.remove(tmp_file)
    return dominant_color

If you don't want to download unnecessary file, do it this way:

# -*- coding: utf-8 -*-

import sys

if sys.version_info < (3, 0):
    from urllib2 import urlopen
else:
    from urllib.request import urlopen

import io

from colorthief import ColorThief


fd = urlopen('http://lokeshdhakar.com/projects/color-thief/img/photo1.jpg')
f = io.BytesIO(fd.read())
color_thief = ColorThief(f)
print(color_thief.get_color(quality=1))
print(color_thief.get_palette(quality=1))
