Edit wp-content/plugins/redux-framework/ReduxCore/inc/fields/color_rgba/field_color_rgba.php

Find this part:

            if ( ! wp_script_is( 'redux-field-color-rgba-js' ) ) {
                wp_enqueue_script(
                    'redux-field-color-rgba-js',
                    ReduxFramework::$_url . 'inc/fields/color_rgba/field_color_rgba' . Redux_Functions::isMin() . '.js',
                    array( 'jquery', 'redux-spectrum-js' ),
                    time(),
                    true
                );
            }

change to:

            if ( ! wp_script_is( 'redux-field-color-rgba-js' ) ) {
                wp_enqueue_script(
                    'redux-field-color-rgba-js',
                    ReduxFramework::$_url . 'inc/fields/color_rgba/field_color_rgba' . Redux_Functions::isMin() . '.js',
                    array( 'jquery', 'redux-spectrum-js', 'redux-js' ),
                    time(),
                    true
                );
            }
