+You can use `.hex('argb')` in [case](https://developer.android.com/reference/android/graphics/Color) you need to encode the color with the alpha channel as first byte rather than the last:

+chroma('orange').hex('argb');; // '#ffffa500'

 ### color.name
 
 Returns the named color. Falls back to hexadecimal RGB string, if the color isn't present.
