python - 从十六进制转换为颜色名称 Python

问题描述

我正在做一个项目，我试图找到图像中使用的不同颜色，我有一个十六进制颜色列表并试图将它们转换为颜色名称。我知道并非所有的十六进制都有与之相关的颜色名称，但我找到了一个带有名称的巨大字典，我正在尝试将它们链接在一起。

我正在尝试将十六进制颜色转换为本词典中的等效名称，该怎么做？

import pandas as pd
from PIL import Image
from collections import Counter

img = Image.open("bnw.jpg")
size = w, h = img.size
data = img.load()

colors = []
for x in range(w):
    for y in range(h):
        color = data[x, y]
        hex_color = '#'+''.join([hex(c)[2:].rjust(2, '0') for c in color])
        colors.append(hex_color)

total = w * h

color_hex = []
color_count = []
color_percent = []

df = pd.DataFrame()
for color, count in Counter(colors).items():
    percent = count/total * \
        100  # Do not make it int. Majority of colors are < 1%, unless you want >= 1%
    if percent > 1:
        color_hex.append(color)
        color_count.append(count)
        color_percent.append(percent)

df['color'] = color_hex
df['count'] = color_count
df['percent'] = color_percent


df.to_excel(r'C:\Users\User\Desktop\Project\export_dataframe.xlsx',
            index=False, header=True)
print('done')

这是字典（这是一半）

解决方案

您可以对 Series使用.apply()方法，对字典使用.get()方法，如下所示：

df_image['color_name'] = df_image['color'].apply(lambda c: colors_dict.get(c, 'Not Found')) # If color isn't in dictionary, then we set 'Not found'.

输出：

    color   count   percent color_name
0   0048BA  1       0.55    Absolute Zero
1   FFAA1D  4       0.43    Bright yellow (Crayola)
2   FFBCD9  6       0.21    Cotton candy
3   556B2F  8       0.73    Dark olive green
4   4N0TH3R 8       0.34    Not Found
