Onsen UI has a wide set of premade themes, which cover a rich set of color combinations. Although the default colors look good, when creating an app with Onsen UI we recommend customizing the theme to give the app a personal touch. Branding is important since it differentiates your app from others and makes it easily recognizable.
How can the developer modify these themes, to give the Onsen UI components the desired colors? There are two ways to accomplish this.
The first one is to use our Theme Roller Tool, which provides, thanks to an intuitive graphical interface, an easy way to customize Onsen UI themes.
The second way to customize themes is by modifying and compiling the Stylus files. Using an automated gulp task and live reloading this approach also powerful and easier to integrate into a normal developer workflow.
