R shinyDashboard customize box status color
<p>I would like to customize the color of the box status of my shiny app. 
I find a css way to change the box background color of these box but not to customize the status color, but I do not see the equivalent argument of "status" in css? 
I thus print the source code of a simple page containing the considered argument "status" and I was lookin at its class (I think class="box box-solid box-primary") but I do not manage to reach it in the several .css provided in this webpage... :(</p>

<p>Do you have an idea ?</p>

<p>Here is this simple code :</p>

<pre><code>library(shiny)
library(shinydashboard)

ui &lt;- dashboardPage(
  dashboardHeader(),
  dashboardSidebar(),
  dashboardBody(
    fluidRow(
      box(width = 6, title = "youhou", status = "primary", solidHeader = TRUE,
          "Box content"
      )
    )
    )
    )


server &lt;- function(input, output) {}

shinyApp(ui, server)
</code></pre>

<p>Thank you in advance for any help !</p>
