Is it possible to annotate with html code? I'm trying to color only a few words and not the entire text.
library(tidyverse)
#> Warning: package 'ggplot2' was built under R version 4.0.2
mtcars %>%
ggplot(aes(x = hp, y = mpg)) +
geom_point() +
annotate(geom = "text", label = "I'm <span style='color: red;'>red</span> \n and i'm <span style='color: orange;'>orange</span>",
x = 250, y = 25)

You can use package 'ggtext'. It is quite new. The only change needed for your example is to replace the geom: using "richtext" instead of "text".

ggplot(aes(x = hp, y = mpg)) +

x = 250, y = 25)
It is possible to use fill = NA to remove the background. To remove the border line label.color = NA can be used.

x = 250, y = 25, fill = NA, label.color = NA)
<span style='background-color:#fff'>, but it did not work.
