color CSS 属性设置颜色值的前景色以及文本装饰，并设置currentcolor (en-US)值。currentcolor可以对其他颜色属性用作不直接的值，比如border-color。

Accessibility concerns
It is important to ensure that the contrast ratio between the color of the text and the background the text is placed over is high enough that people experiencing low vision conditions will be able to read the content of the page.
Color contrast ratio is determined by comparing the luminosity of the text and background color values. In order to meet current Web Content Accessibility Guidelines (WCAG), a ratio of 4.5:1 is required for text content and 3:1 for larger text such as headings. Large text is defined as 18.66px and bold or larger, or 24px or larger.

示例
使文本为红色
以下方式可以使得文本显示为红色：
p { color: red; }
p { color: #f00; }
p { color: #ff0000; }
p { color: rgb(255,0,0); }
p { color: rgb(100%, 0%, 0%); }
p { color: hsl(0, 100%, 50%); }
/* 50% 透明 */
p { color: #ff000080; }
p { color: rgba(255, 0, 0, 0.5); }
p { color: hsla(0, 100%, 50%, 0.5); }
