Problem
You want to use colors in a graph with ggplot2.
Solution
The default colors in ggplot2 can be difficult to distinguish from one another because they have equal luminance. They are also not friendly for colorblind viewers.
A good general-purpose solution is to just use the colorblind-friendly palette below.
Sample data
These two data sets will be used to generate the graphs below.
Simple color assignment
The colors of lines and points can be set directly using
colour='red'
, replacing “red” with a color name. The colors of filled objects, like bars, can be set using fill='red'
.If you want to use anything other than very basic colors, it may be easier to use hexadecimal codes for colors, like
'#FF6699'
. (See the hexadecimal color chart below.)Mapping variable values to colors
Instead of changing colors globally, you can map variables to colors – in other words, make the color conditional on a variable, by putting it inside an
aes()
statement.A colorblind-friendly palette

These are color-blind-friendly palettes, one with gray, and one with black.
To use with ggplot2, it is possible to store the palette in a variable, then use it later.

Color selection
By default, the colors for discrete scales are evenly spaced around a HSL color circle. Fantastical 2 5 15 birthdays. For example, if there are two colors, then they will be selected from opposite points on the circle; if there are three colors, they will be 120° apart on the color circle; and so on.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:Setting luminance and saturation (chromaticity)
Although
scale_fill_hue()
and scale_colour_hue()
were redundant above, they can be used when you want to make changes from the default, like changing the luminance or chromaticity.This is a chart of colors with luminance=45:
Palettes: Color Brewer
You can also use other color scales, such as ones taken from the RColorBrewer package. See the chart of RColorBrewer palettes below. See the scale section here for more information.
Palettes: manually-defined
Finally, you can define your own set of colors with
scale_fill_manual()
. See the hexadecimal code chart below for help choosing specific colors.Continuous colors

Colors can specified as a hexadecimal RGB triplet, such as
'#0066CC'
. The first two digits are the level of red, the next two green, and the last two blue. The value for each ranges from 00 to FF in hexadecimal (base-16) notation, which is equivalent to 0 and 255 in base-10. For example, in the table below, “#FFFFFF” is white and “#990000” is a deep red.![Colored 1 2 2 – Create Color Palettes List Colored 1 2 2 – Create Color Palettes List](https://andrewflintdesignchronicles.files.wordpress.com/2015/05/colour-palette-2-colours.png?w=768)
