Format style of grouped bar names in ggplot2

How can I format the style of the grouped bar names in ggplot2? I would like to change the text color from grey to black. I've added a picture to clarify what I mean.

What I've got so far:

specify_decimal <- function(x, k) trimws(format(round(x, k), nsmall=k))
library(ggplot2)

ggplot(data, aes(type, hitrate, fill=Cache)) + 
geom_bar(position=position_dodge(0.9), width=0.8, stat="identity") +
geom_errorbar(aes(ymin=hitrate-sd, ymax=hitrate+sd),width=0.3,position=position_dodge(0.9)) + 
coord_cartesian(ylim = c(0, 0.8)) + 
theme(axis.title.x=element_blank(),axis.ticks.x=element_blank()) + 
scale_y_continuous(name="Hit Ratio") + 
scale_fill_brewer(palette = "Set1") + geom_text(aes(label=specify_decimal(hitrate,8)), position=position_dodge(width=0.9), vjust=-0.45)

Many thanks!

Adjust your theme settings:

library(ggplot2)
ggplot(mpg, aes(class)) + 
  geom_bar() + 
  theme(axis.text.x = element_text(color = "red"))
