 *
 * The helper does the following:

 * * It sets the color input `id` and `ariaDescribedById` attributes.
 * * It binds the color input `isReadOnly` to the labeled view.

 * * It enables a logic that cleans up the error when the user starts typing in the color input.

 *

 * const colorInputCreator = getLabeledColorInputCreator( {
 *   colorConfig: [ ... ],
 *   columns: 3,
 * } );
 *
 * const labeledInputView = new LabeledFieldView( locale, colorInputCreator );

 * @param options.colorConfig The configuration of the color palette displayed in the input's dropdown.
 * @param options.columns The configuration of the number of columns the color palette consists of in the input's dropdown.
