词语的颜色（定理、定义、事实）

Question

LyX 使用提供的样式amsthm，即和plain，因此您可以通过将以下内容添加到来修改这些样式（有关的解释，请参阅的文档，有关我使用的值，请参阅definitionremarkDocument->Settings->LaTeX Preamble\newtheoremstyleamsthm这个答案）

\newtheoremstyle{plain}
  {\topsep}   % ABOVESPACE
  {\topsep}   % BELOWSPACE
  {\itshape}  % BODYFONT
  {0pt}       % INDENT (empty value is the same as 0pt)
  {\color{red}\bfseries} % HEADFONT
  {.}         % HEADPUNCT
  {5pt plus 1pt minus 1pt} % HEADSPACE
  {}       

\newtheoremstyle{definition}
  {\topsep}   % ABOVESPACE
  {\topsep}   % BELOWSPACE
  {\normalfont}  % BODYFONT
  {0pt}       % INDENT (empty value is the same as 0pt)
  {\color{red}\bfseries} % HEADFONT
  {.}         % HEADPUNCT
  {5pt plus 1pt minus 1pt} % HEADSPACE
  {}     

\newtheoremstyle{remark}
  {.5\topsep}   % ABOVESPACE
  {.5\topsep}   % BELOWSPACE
  {\normalfont}  % BODYFONT
  {0pt}       % INDENT (empty value is the same as 0pt)
  {\color{red}\itshape} % HEADFONT
  {.}         % HEADPUNCT
  {5pt plus 1pt minus 1pt} % HEADSPACE
  {}

要更改编辑器中的显示，您需要Document->Settings->Local Layout为每个类似定理的环境添加以下几行（对于类似定理的注释，形状为斜体，形状不是粗体）

ModifyStyle Theorem
LabelFont
Shape               Up
Series              Bold
Color   red
EndFont
End

要理解此语法的含义，请阅读手册的第 5.3 节Help->Customization。

 Convergence & Divergence of Series
\end_layout

\begin_layout Definition
Let 
\begin_inset Formula $\sum_{n=1}^{\infty}a_{n}$
\end_inset

 a series, we call the sequence 
\begin_inset Formula $\left\{ s_{n}\right\} _{n=1}^{\infty}$
\end_inset

 the partial sums sequence.
\end_layout

\begin_layout Section
Divergence Test
\end_layout

\begin_layout Standard
Notice that for the two series that converged the series term itself was
 zero in the limit.
 This will always be true for convergent series and leads to the following
 theorem.

Theorem
\end_layout

\end_inset

 If 
\begin_inset Formula $\sum a_{n}$
\end_inset

 converges then 
\begin_inset Formula $\lim_{n\rightarrow\infty}a_{\mathrm{n}}=0$
\end_inset

.

\begin_layout Fact
Facts.
 Given the series 
\begin_inset Formula $\sum a_{n}$
\end_inset

, 
\begin_inset Newline newline
\end_inset

1.
 If 
\begin_inset Formula $\sum a_{n}$
\end_inset

 is absolutely convergent and its value is 
\begin_inset Formula $s$
\end_inset

 then any rearrangement of 
\begin_inset Formula $\sum a_{n}$
\end_inset

 will also have a value of 
\begin_inset Formula $s$
\end_inset

.
\begin_inset Newline newline
\end_inset

2.
 If 
\begin_inset Formula $\sum a_{n}$
\end_inset

 is conditionally convergent and 
\begin_inset Formula $r$
\end_inset

 is any real number then there is a rearrangement of 
\begin_inset Formula $\sum a_{n}$
\end_inset

 whose value will be 
\begin_inset Formula $r$
\end_inset

.
