问题：给定目标 RGB 颜色，如何重新着色黑色 ( #000) 仅使用 CSS 滤镜转换为该颜色？
解决方案： 使用以下函数将目标 RGB 颜色转换为 CSS 滤镜字符串：
<code class="python">def css_filter(target_color):
"""Converts a target RGB color into a CSS filter string.
Args:
target_color: A tuple of three integers representing the target RGB color.
Returns:
A CSS filter string that transforms black into the target color.
"""
# Convert the target RGB color to HSL.
h, s, l = colorsys.rgb_to_hls(*target_color)
# Calculate the CSS filter values.
invert = 1 - (l / 100)
sepia = 1 - s
saturate = s / 100
hue_rotate = h * 360
brightness = l
contrast = 1
# Return the CSS filter string.
return "filter: invert({0}%) sepia({1}%) saturate({2}%) hue-rotate({3}deg) brightness({4}%) contrast({5});".format(
invert, sepia, saturate, hue_rotate, brightness, contrast)</code>以上是如何使用 CSS 滤镜重新着色黑色以匹配任何 RGB 颜色？的详细内容。更多信息请关注PHP中文网其他相关文章！
