Colors; got to get them all!

Make your attributes

The theme

Let’s look at the content background color full chain to clarify

// file: values/palette_spec.xml 
// Here I specify all colors allowed
<color name="c1">#212121</color> // almost black
<color name="c5">#FAFAFA</color> // almost white
// file: values/palette.xml
// And the light mode specific palette
<color name="mode_color_background">@color/c5</color>
// file: values-night/palette.xml
// And the light mode specific palette
<color name="mode_color_background">@color/c1</color>
// file: values/attrs.xml
// The styled attribute to be used by the views
<attr name="themeContentBackground" format="color" />
// file: values/theme.xml
// And in our theme that connect our attributes with colors
<item name="themeContentBackground">

Make our views depend on the theme
