Affect of Color Property on Borders and Oulines

The color property is not just for text content, but for anything in the foreground that takes a color value. For instance, if border-color or outline-color value hasn’t been defined explicitly for the element, the color value will be used instead.

[css]

p.one {
color: #0000ff;
border: 2px solid;
}
p.two {
color: #00ff00;
outline: 2px solid;
}
