How to set the color of se(confidence interval) of geom_smooth in ggplot2?

Question

When I set the function, geom_smooth(..., se = TURE), the confidence interval is gray, but I want to set some other color.

Looks like it is a parameter that can not set color in geom_smooth. Should I create a new geom? or are there some ggplot2 extensions can be used? Thank you

Solution

Since you did not provide example data

ggplot(
    iris, 
    aes(
        x = Sepal.Length, 
        y = Sepal.Width
    )
) + 
    geom_point() + 
    geom_smooth(fill = "red")
