从十六进制转换为颜色名称Python

import colorsys

def hex_to_color_name(hex_value):
    # 去掉十六进制值中的井号
    hex_value = hex_value.lstrip('#')

    # 将十六进制值转换为RGB值
    rgb = tuple(int(hex_value[i:i+2], 16) for i in (0, 2, 4))

    # 将RGB值转换为HSV值
    hsv = colorsys.rgb_to_hsv(rgb[0]/255, rgb[1]/255, rgb[2]/255)

    # 根据HSV值确定颜色名称
    if hsv[1] < 0.1:
        return '黑色'
    elif hsv[2] > 0.9:
        return '白色'
    elif hsv[2] < 0.2:
        return '黑色'
    elif hsv[0] < 0.0417:
        return '红色'
    elif hsv[0] < 0.125:
        return '橙色'
    elif hsv[0] < 0.2083:
