I'm using Metronic 8 React Version. I want to change the primary color of the application. Tried doing it by overiding and setting the ($primary) variable in '_variables.custom.scss' file. Presently, its a purple shade (#7239ea), would like to change it to blue (#304294). The color is not changing. Tried running the app again, still no results.

In '_variables.custom.scss' file -

// $primary: #7239ea;
$primary: #304294;
