The answer given at the link provided by @Ben Bolker:

<pre><code>Roses are &lt;span style="color:red"&gt;red&lt;/span&gt;, 
violets are &lt;span style="color:blue"&gt;blue&lt;/span&gt;.
</code></pre>

does work if you select HTML (ioslides) as the output format.

However, it does not work if you select pdf (beamer) as output format. If you want to create a pdf, use LaTeX syntax:

<pre><code> Roses are \textcolor{red}{red}, violets are \textcolor{blue}{blue}.
</code></pre>

blocks|key|18561|text|我创建了一个这样的函数：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|18562|##+Color+Format
colFmt+<-+function(x,color)+{

++}+else+{
++++ret+<-+x
++}

++return(ret)
}|code-block|syntax|javascript|18563|然后，您可以像这样内联使用它：`r+colFmt("MY+RED+TEXT",'red')`，并且无论是在latex还是HTML上工作，都将呈现彩色文本。|offset|length|style|CODE|18564|entityMap^0|0|0|F|V|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

I create a function like this:
<pre><code>## Color Format
colFmt &lt;- function(x,color) {
 
 outputFormat &lt;- knitr::opts_knit$get(&quot;rmarkdown.pandoc.to&quot;)
 
 if(outputFormat == 'latex') {
 ret &lt;- paste(&quot;\\textcolor{&quot;,color,&quot;}{&quot;,x,&quot;}&quot;,sep=&quot;&quot;)
 } else if(outputFormat == 'html') {
 ret &lt;- paste(&quot;&lt;font color='&quot;,color,&quot;'&gt;&quot;,x,&quot;&lt;/font&gt;&quot;,sep=&quot;&quot;)
 } else {
 ret &lt;- x
 }

 return(ret)
}
</code></pre>
Then you can use it inline like this:<code>`r colFmt(&quot;MY RED TEXT&quot;,'red')`</code>, and colored text will be rendered regardless of whether working on latex or HTML document.

blocks|key|18675|text|这似乎在pdf和html这两种输出格式中都能很好地工作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|18676|Roses+are+$\color{red}{\text{beautiful+red}}$,+

This seems to work very well in both output formats, pdf and html:

Hope it helps.

blocks|key|18694|text|输出格式不可知的解决方案是使用kableExtra包中的专用text_spec()函数：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|18695|Roses+are+`r+kableExtra::text_spec("red",+color+=+"red")`,

An output-format agnostic solution would be to use the dedicated <code>text_spec()</code> function in the <code>kableExtra</code> package:

<pre><code>Roses are `r kableExtra::text_spec("red", color = "red")`,

violets are `r kableExtra::text_spec("blue", color = "blue")`
</code></pre>

blocks|key|18651|text|其他人已经为Word之外的输出提供了答案。对于Word，您可以使用Pandoc自定义样式语法在参考word文档的帮助下完成此操作。首先，在您的reference.docx模板中，使用简短的独特名称创建一个新的Word样式。如果要将字体颜色应用于整个段落，则可以使用默认的“链接段落和字符”样式类型。如果只想用颜色强调段落中的某些单词，则需要选择“字符”样式类型。更改字体颜色(以及所需的任何其它样式)并保存reference.docx文件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|18652|然后，在.Rmd文件中，您可以按如下方式使用标记：|18653|<div+custom-style=“DivCol”>Whole+paragraph+of+colored+text</div>

Just+a+<span+custom-style=“SpanCol”>few+words+of+colored+text|code-block|syntax|javascript|18654|关于样式名称的一句话-由于我不明白的原因，这个过程不适用于样式名称“Span_Add”，但“SpanAdd”可以。|18655|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

Others have provided answers for output other than Word. For Word, you can use the Pandoc custom-style syntax to accomplish this with the aid of a reference word document. First, inside your reference.docx template, create a new Word style with a short, distinct name. If you want your font color to apply to a full paragraph, you can use the default, “Linked Paragraph and Character” style type. If you only want to emphasize some words in a paragraph with color, you need to select the “Character” style type. Change the font color (and any other styling you need) and save the reference.docx file.

Then, inside your .Rmd file, you can use the tag as follows:

<pre><code>&lt;div custom-style=“DivCol”&gt;Whole paragraph of colored text&lt;/div&gt;

Just a &lt;span custom-style=“SpanCol”&gt;few words&lt;/span&gt; of colored text
</code></pre>

A word regarding style names - for reasons I don’t understand, this process did not work with the style name “Span_Add” but “SpanAdd” was fine.

blocks|key|18614|text|我基本上使用了Nicholas+Hamilton的答案，但是因为我使用了xtable和print，所以我在转义某些latex序列时遇到了一些问题。也就是说，将\\textcolor转换为$\backslash$textcolor。我通过以下方式避免了杀毒，从而获得了正确的结果：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|18615|```{r+results='asis'}|code-block|syntax|javascript|18616|tbl+=+data.frame(a+=字母1:10，b=1:10/+10)|18617|tbl$b+=+ifelse(tbl$b+<+0.5，colFmt(tbl$b，“红色”)，colFmt(tbl$b，“绿色”))|18618|print(xtable(tbl)，sanitize.text.function+=标识)|18619|18620|然后，我不得不手动清理一些字符，比如%25，但至少\textcolor是正确应用的。当然，这可以通过扩展您自己的sanitize函数来避免。|18621|entityMap^0|10|6|17|5|27|B|2L|L|0|0|0|0|0|0|I|1|N|A|0^^$0|@$1|2|3|4|5|6|7|V|8|@$9|W|A|X|B|C]|$9|Y|A|Z|B|C]|$9|10|A|11|B|C]|$9|12|A|13|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|14|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|15|8|@]|D|@]|E|$]]|$1|M|3|N|5|6|7|16|8|@]|D|@]|E|$]]|$1|O|3|P|5|6|7|17|8|@]|D|@]|E|$]]|$1|Q|3|-4|5|H|7|18|8|@]|D|@]|E|$I|J]]|$1|R|3|S|5|6|7|19|8|@$9|1A|A|1B|B|C]|$9|1C|A|1D|B|C]]|D|@]|E|$]]|$1|T|3|-4|5|6|7|1E|8|@]|D|@]|E|$]]]|U|$]]

I basically used Nicholas Hamilton's answer but because I used <code>xtable</code> and <code>print</code>, I had some problems with certain latex sequences being escaped. Namely, <code>\\textcolor</code> being transformed to <code>$\backslash$textcolor</code>. I was able to get it right by avoiding sanitizing in the following way:

<pre><code>```{r results='asis'}
tbl = data.frame(a = letters[1:10], b = 1:10 / 10)
tbl$b = ifelse(tbl$b &lt; 0.5, colFmt(tbl$b, "red"), colFmt(tbl$b, "green"))
print(xtable(tbl), sanitize.text.function = identity)
```
</code></pre>

I then had to go and manually sanitize a few characters like <code>%</code> but at least <code>\textcolor</code> was correctly applied. Of course, this could be avoided by expanding your own sanitize function.

blocks|key|18712|text|对于PDF和HTML，要获得彩色文本，可以使用标记高亮显示进行修改：see+the+rmarkdown+book。Pandoc滤波器是最好的选择。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|18713|对于Microsoft+word，您必须首先创建一个具有自定义样式的Template_MS.docx。警告:为段落添加颜色(段落样式)和为少量单词(字符样式)添加颜色创建不同的样式。这是您创建新样式时的一个选项。|18714|在YAML中添加：|18715|---++++++

For PDF and HTML, to get colored text which you can modify with markdown highlighting : <a href="https://bookdown.org/yihui/rmarkdown-cookbook/font-color.html" rel="nofollow noreferrer">see the rmarkdown book</a>. Pandoc filter is the best choice. 

For Microsoft word, you have to create first a Template_MS.docx with custom styles. Warning: create different styles for coloring paragraphs (paragraph style) and for colorings few words (character style). It is an option when you made a new style.

Add in th YAML: 

<pre><code>--- 
output: 
 word_document: 
 reference_docx: Template_MS.docx 
--- 
</code></pre>

And next: 

<pre><code>For &lt;span custom-style="Character1"&gt;few words&lt;/span&gt; of colored text.
</code></pre>

For paragraph.

<pre><code>&lt;div custom-style="Paragraph1"&gt;Paragraph of colored text. Blabla. Blabla.&lt;/div&gt; 
</code></pre>

Nota Bene: 
+ Do not use the same style for Paragraph and a few words, it is bugging. 
+ If it is not working, check that your style is for paragraph ou character in MS. 
+ If it is not working, install an updated version of pandoc.

In RMarkdown is there a way to specify the font color? 

There doesn't seem to be an option while browsing through the <a href="http://yihui.name/knitr/options/#chunk_options">chunk options</a>
