可以通过 bar本身为透明色，但是我需要颜色顺序按照配置的colors展示，设置透明色会导致，第2个柱子（没有贴纸）的颜色实际使用的是第一个颜色， 需要不断地重新计算对应的 color

You can use the bar itself as a transparent color, but I need the color order to be displayed according to the configured colors, setting the transparent color will cause the color of the second column (without stickers) to actually use the first color, and the corresponding color needs to be constantly recalculated
