Ggplot Color Fill. You can change the colour using the scale_fill_ functions. To display values, map variables in the data to visual properties of the geom (aesthetics) like size, color, and x and y locations.
This changes the color of the line or points [fill]{.underline}: Whenever we map color or fill as an aesthetic, ggplot2 uses a default color scheme, known as the color or fill scales in the grammar of graphics. They are also not friendly for colorblind viewers.
When You Use A Variable (Column) Inside Aes To Set An Aesthetic (I.e.

If the shape is filled, this changes the fill color. The colour aesthetic is used to draw lines and strokes, such as in geom_point() and geom_line(), but also the line contours of geom_rect() and geom_polygon(). Hue [0,360], chroma [0,100], and luminance [0,100].

You use the color attribute to change the outline of a shape and you use the fill attribute to fill the inside of a shape. Specifically, we use the color attribute to change the color. If the shape is filled, this changes the fill color.
The Colour Aesthetic Is Used To Draw Lines And Strokes, Such As In Geom_Point() And Geom_Line(), But Also The Line Contours Of Geom_Rect() And Geom_Polygon().
Work on the aesthetics specified in the scale name: Filled shapes are used in bar plots, box plots, and histograms. Almost every geom has either colour, fill, or both.
