2.1. Color

Use the ImageEnhance.Color(image).enhance(factor) method to return an image with adjusted colour.

ImageEnhance.Color(image).enhance(factor)

factor is a floating point value controlling the enhancement. There are no restrictions on this value.

Factor 1.0 always returns a copy of the original image.

lower factors mean less color, and higher values more.

The code below creates several images of various color enhancement factors.

from PIL import Image, ImageEnhance


with Image.open("test_images/alph_blocks.png") as im:
    new_im = ImageEnhance.Color(im).enhance(0)
    new_im.save("enhanced/color0.png")
    new_im = ImageEnhance.Color(im).enhance(0.5)
    new_im.save("enhanced/color0_5.png")
    new_im = ImageEnhance.Color(im).enhance(1)
    new_im.save("enhanced/color1.png")
    new_im = ImageEnhance.Color(im).enhance(2)
    new_im.save("enhanced/color1_3.png")
    new_im = ImageEnhance.Color(im).enhance(10)
    new_im.save("enhanced/color2.png")
