如何提取文件中具有特殊颜色css规则

import re

def extract_special_color_rules(css_file_path):
    special_color_rules = []

    with open(css_file_path, 'r') as css_file:
        css_content = css_file.read()

        # 使用正则表达式匹配CSS规则
        pattern = r'([^{]+){([^}]+color:[^;}]+;[^}]+)}'
        matches = re.findall(pattern, css_content)

        for match in matches:
            selector = match[0].strip()
            properties = match[1].strip()

            # 检查颜色属性
            if 'color:' in properties:
                color_value = re.search(r'color:\s*([^;]+)', properties).group(1)
                special_color_rules.append((selector, color_value))

    return special_color_rules

# 示例用法
css_file_path = 'styles.css'
special_color_rules = extract_special_color_rules(css_file_path)

for rule in special_color_rules:
    selector, color_value = rule
    print(f'Selector: {selector}')
    print(f'Color value: {color_value}')
    print('---')
