Not able to create blue caption for my figure

I'm trying to create blue caption for my figure, but I get the error message

ERROR: 
compilation failed- missing packages (automatic installed disabled)
Undefined control sequence.
<recently read> \DeclareCaptionFont 
                    
l.97 \DeclareCaptionFont
                      {blue}{\color{blue}}

Then I try to render my code. Any ideas why this does not work?

      - text: | 
           \usepackage{geometry}
           \usepackage{color}
           \DeclareCaptionFont{blue}{\color{blue}}
           \usepackage[font=Large,labelfont = bf,textfont = {blue,sf}]{caption}

```{r, figure, fig.height= 12, fig.width= 10,fig.cap=paste("Blue Caption")}
#| echo: false
library(tidyverse)


 data.frame(Year= 2000:2002, 
            length=c(4.2, 10, 29.5)) %>% 
  ggplot() + geom_line(mapping = aes(x = Year, y = length))

```

You need to load the caption package if you want to use macros from this package like \DeclareCaptionFont:
