color
The color extension defines the \color
macro as in the LaTeX
color package, along with \colorbox
, \fcolorbox
, and
\definecolor
. It declares the standard set of colors (Apricot,
Aquamarine, Bittersweet, and so on), and provides the RGB, rgb,
and grey-scale color spaces in addition to named colors.
This extension is loaded automatically when the autoload extension
is used. To load the color extension explicitly, add
'[tex]/color'
to the load
array of the loader
block of
your MathJax configuration, and add 'color'
to the packages
array of the tex
block.
window.MathJax = {
loader: {load: ['[tex]/color']},
tex: {packages: {'[+]': ['color']}}
};
Alternatively, use \require{color}
in a TeX expression to load it
dynamically from within the math on the page, if the require
extension is loaded.
Note
In version 2, a non-standard \color
macro was the default
implementation, but in version 3, the standard LaTeX one is now the
default. The difference between the two is that the standard
\color
macro is a switch (everything that follows it is in the
new color), whereas the non-standard version 2 \color
macro
takes an argument that is the mathematics to be colored. That is,
in version 2, you would do
\color{red}{x} + \color{blue}{y}
to get a red x added to a blue y. But in version 3 (and in LaTeX itself), you would do
{\color{red} x} + {\color{blue} y}
If you want the old version 2 behavior, use the colorV2 extension instead.
