Question

我只想给文档中选定的文本涂上颜色。但是，即使我指定仅在括号{}中应用颜色（尤其是蓝色），我的文档的其余部分都变成了蓝色。

我尝试使用\par甚至\quad。它没有用。

当我尝试\textcolor{blue}{my text}时，它仅适用于该特定实例。

但是，当我尝试


    \color{blue}__Answer:__

    1+1

    $$
    x_1 + x_2 = 2x_3^{2}
    $$

    \quad

该文本块显示为蓝色，文档的其余部分也显示为蓝色，这不是我想要的。

以下是我的Rmarkdown文档中的内容

Question 1

Let $x_1$ and $x_2$ be two random variables with covariance matrix:
$$
\boldsymbol{\Sigma} =
\begin{pmatrix}
    7        & \sqrt{5} \\
    \sqrt{5} & 3
\end{pmatrix}
$$Find the principal components (eigenvalues and eigenvectors) and compute the percentage of the total variance explained by each component.

\color{blue}__Answer:__

$$
x_1 + x_2 = 2x_3^{2}
$$

\quad

Question 2:

Answer 1

如果在紧接“问题2”之前的\color{black}之后添加\quad，那应该可以达到预期的效果。


\color{blue}__Answer:__

$$
x_1 + x_2 = 2x_3^{2}
$$
