# Color in equations

Test 1: 

```
$${\color{#0271AE}{\int dx e^-x}}$$ 
```

yields

$$
{\color{#0271AE}{\int dx e^-x}}
$$ 

Test 2: 

```
$$(x={\color{#DC2830}{c_1}} \cdot {\color{#0271AE}{x_1}} + {\color{#DC2830}{c_2}} \cdot {\color{#0271AE}{x_2}})$$
```
yields

$$
(x={\color{#DC2830}{c_1}} \cdot {\color{#0271AE}{x_1}} + {\color{#DC2830}{c_2}} \cdot {\color{#0271AE}{x_2}})
$$

Test macro: 

```
$$
A = \bmat{} 1 & 1 \\ 2 & 1\\ 3 & 2 \emat{},\ b=\bmat{} 2\\ 3 \\ 4\emat{},\ \gamma = 0.5
$$
```

yields

$$
A = \bmat{} 1 & 1 \\ 2 & 1\\ 3 & 2 \emat{},\ b=\bmat{} 2\\ 3 \\ 4\emat{},\ \gamma = 0.5
$$

test sphinx shortcut for color 

```$$\bered{\int dx e^-x}$$```

yields

$$
\bered{\int dx e^-x}
$$
