# Find most used colors in image using Python

• Last Updated : 16 Oct, 2021

Prerequisite: PIL

PIL is the Python Imaging Library which provides the python interpreter with image editing capabilities. It was developed by Fredrik Lundh and several other contributors. Pillow is the friendly PIL fork and an easy-to-use library developed by Alex Clark and other contributors. We’ll be working with Pillow.

Let’s understand with step-by-step implementation:

For reading the image in PIL, we use Image method.

```# Read an Image
img = Image.open('File Name')```

2. Convert into RGB image

`img.convert('RGB')`

3. Get Width and Height of Image

`width, height = img.size`

4. Iterate through all pixels of Image and get R, G, B value from that pixel

```for x in range(0, width):
for y in range(0, height):
r, g, b = img.getpixel((x,y))
print(img.getpixel((x,y)))```

Output:

(155, 173, 151), (155, 173, 151), (155, 173, 151), (155, 173, 151), (155, 173, 151) …

5. Initialize three variable

• r_total = 0
• g_total = 0
• b_total = 0

Iterate through all pixel and add each color to different Initialized variable.

```r_total = 0
g_total = 0
b_total = 0

for x in range(0, width):
for y in range(0, height):
r, g, b = img.getpixel((x,y))
r_total += r
g_total += g
b_total += b
print(r_total, g_total, b_total)```

Output:

`(29821623, 32659007, 33290689)`

As we can R, G & B value is very large, here we will use count variable

Initialize One More variable

count = 0

`Divide total color value by count`

Below is the Implementation:

Image Used –

## Python3

 `# Import Module``from` `PIL ``import` `Image` `def` `most_common_used_color(img):``    ``# Get width and height of Image``    ``width, height ``=` `img.size` `    ``# Initialize Variable``    ``r_total ``=` `0``    ``g_total ``=` `0``    ``b_total ``=` `0` `    ``count ``=` `0` `    ``# Iterate through each pixel``    ``for` `x ``in` `range``(``0``, width):``        ``for` `y ``in` `range``(``0``, height):``            ``# r,g,b value of pixel``            ``r, g, b ``=` `img.getpixel((x, y))` `            ``r_total ``+``=` `r``            ``g_total ``+``=` `g``            ``b_total ``+``=` `b``            ``count ``+``=` `1` `    ``return` `(r_total``/``count, g_total``/``count, b_total``/``count)` `# Read Image``img ``=` `Image.``open``(r``'C:\Users\HP\Desktop\New folder\mix_color.png'``)` `# Convert Image into RGB``img ``=` `img.convert(``'RGB'``)` `# call function``common_color ``=` `most_common_used_color(img)` `print``(common_color)``# Output is (R, G, B)`

Output:

```# Most Used color is Blue
(179.6483313253012, 196.74100602409638, 200.54631927710844)```
