A Real Time Skin Selector

{bs4Dash} has a new feature called the skinSelector(). This is a JavaScript based widget allowing the end user to change the app skin. There are 20 unique colors with 2 versions, light or dark. Note that the dashboardControlbar() is the perfect place to host the skinSelector().

Fresh

{fresh} is developed by the dreamRs team. It is built on top of {sass}, which provides a solid R API to write SASS variables and compile into CSS. {fresh} captures most of the AdminLTE2 (as well as AdminLTE3 for Bootstrap 4) SASS variables to allow deep customization, hiding all the compilation burden under the hood.

bs4dash_color() and bs4Dash_status() provide an interface to all available AdminLTE colors and allow to overwrite the default. I strongly suggest to avoid setting the default green to blue, as it might become confusing. Instead, it is better to play with color palettes. bs4dash_sidebar_light() allows to re-style the sidebar component, bs4dash_layout() controls the main background color, bs4dash_yiq() fine tune the global contrast and bs4dash_vars() offers deeper customization (navbar, ...). The fresh theme below is based on some dark theme color palettes.
