色度滤镜用于使任何特定颜色透明，通常用于图像。您也可以将其与滚动条一起使用。
实施CSS色度过滤器-
<html> <head> </head> <body> <img src = "/images/css.gif" alt = "CSS Logo" style = "Filter: Chroma(Color = #FFFFFF)"> <p>Text Example:</p> <div style = "width: 580; height: 50; font-size: 30pt; font-family: Arial Black; color: #3300FF; Filter: Chroma(Color = #3300FF)">CSS Tutorials</div> </body> </html>
