How do you change the color of an icon in an R Shiny app?

Question

I have a Shiny app that uses a couple icons from the Font Awesome library (built-in) in the UI:

icon("bolt")

icon("compass")

How do I change the color of each icon?

Answer 1

At the beginning of the UI, insert tags$style(".fa-bolt {color:#E87722}") to change the color of the bolt icon. Similarly, add tags$style(".fa-compass {color:#E87722}") to change the color of the compass icon. This will apply the coloring to all bolt icons and compass icons in the app.

Answer 2

You can just use HTML tags instead of using icon()

tags$i(
    class = "fa fa-check-square", 
    style = "color: rgb(0,166,90)"
)

eg

library(shiny)

ui <- fluidPage(
    tags$p("icon:"),
    tags$hr(),
    tags$i(
        class = "fa fa-check-square", 
        style = "color: rgb(0,166,90)"
    ),
    icon("check-square")
)

server <- function(input, output, session) {

}

shinyApp(ui, server)
