我正在使用KartikV颜色输入部件为Yii2高级，我有很多的颜色输入字段在我的形式。我如何才能得到新的选择颜色的值后，每次选择不同的颜色输入。这主要是我需要选择颜色的一些选项，并在画布上绘制与此选定的颜色。之后，我必须从不同的输入中选择另一种颜色，并继续在画布上绘制，但现在使用新选择的颜色值。用于绘图的jQuery脚本已经准备好了，但是需要在每次输入更改后分配选定的颜色。
一个颜色选择行的示例：

<div class="row skin-condition-select-sections">
                                <div class="col-md-4">

                                            'showDefaultPalette' => false,
