// Used by `ColorPicker`, `DatePicker`, `EditView`, `NumberPicker`, `TimePicker`.
//
// Usage in `ColorPicker`:
// List of pre-defined colors.

// `uint64`.
//
// Internal type is `[]string`, other types converted to it during assignment.
//
// Conversion rules:
// `string` - contain single item.
// `[]string` - an array of items.
