Here is an example of how you can formulate queries related to theme-related colors using gg_
-commands:
ggplot(data=iris,
mapping=aes(x=Sepal.Length,
y=Petal.Length, color=Species))+
ggtitle("Iris")+
geom_point()+
gg_("paint the title red")+
gg_("paint the x-axis label in green")+
gg_("also, I want a purple y-axis label")
