# Colors

Here is an example of how you can formulate queries related to theme-related colors using `gg_`-commands:

```{r message=FALSE}
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")
```


# Valid Colors

The `ggx` package matches valid base R colors. The list of all valid colors, such as those:

```{r}
head(colors(), n=20)
```
