The colors used for different numbers of levels are shown here: The default color selection uses scale_fill_hue() and scale_colour_hue(). For example, adding those commands is redundant in these cases: # These two are equivalent; by default scale_fill_hue() is used ggplot(df, aes(x=...

Colors can be specified as a hexadecimal RGB triplet, such as "#FFCC00" or by names (e.g : "red" ). You can also use other color scales, such as ones taken from the RColorBrewer package. The different color systems available in R have been described in detail here. ...
To changehistogram plotcolor according to the group, you have to specify the name of the data column containing the groups using the argumentgroupName. Use the argumentgroupColors, to specify colors byhexadecimalcode or byname. In this case, the length of groupColors should be the same as the...
