/**
 * Increases the intensity of a color. Its range is between 0 to 1. The first

 * intensity should be increased.

 * @example
 * // Styles as object usage
 * const styles = {
 *   background: saturate(0.2, '#CCCD64'),
 *   background: saturate('0.2', 'rgba(204,205,100,0.7)'),

 *
 * // styled-components usage
 * const div = styled.div`
 *   background: ${saturate(0.2, '#FFCD64')};
 *   background: ${saturate('0.2', 'rgba(204,205,100,0.7)')};
 * `

 * // CSS in JS Output
