How can I modify the color of cross-referencing in the R markdown generated pdf document? - pdf

Question

---
title: "Annual Report"
author: "Xyz"
date: "`r format(Sys.time(),'%d %B, %Y')`"
output:
bookdown::pdf_document2:
extra_dependencies: ["float"]
number_sections: false
toc: false
linkcolor: blue

```{r, echo = FALSE}
library(ggplot2)
data(mtcars)
names(mtcars)
```
### Heading 1
```{r figure-1,echo=FALSE, fig.cap = "Sample Graph 1"}
ggplot(mtcars,aes(x=mpg,y=hp))+
geom_point()+
theme_classic()
```
To see another graph, please see figure \textcolor{blue}{\#ref(fig:figure-2)}
\newpage
### Heading 2
```{r figure-2,echo=FALSE, fig.cap = "Sample Graph 2"}
ggplot(mtcars,aes(x=mpg,y=carb))+
geom_point()+
theme_classic()
```
To see another graph, please see figure \#ref(fig:figure-1)
After execution, I found the following in knitted pdf document before Heading 2.
To see another graph, please see figure reffig:figure-2
reffig:figure in the code is not cross-referenced as well. What I want is that my document should show the following line in the pdf document:
To see another graph, please see figure 2
"2" in the above statement should be hyperlinked and its color should be blue, enabling the reader to jump to figure 2 if user clicks on "2".

Adding urlcolor:blue to your yaml should work.
