I can only find ColorPicker in ArcGIS JavaScript API 3.X, but I'm working on a project using 4.12.

I'm trying to implement ColorPicker to my map to let users to choose colors for Sketch objects.

I've included both 4.12 and 3.29 APIs in my code as well as required "esri/dijit/ColorPicker", then the website just turned into a blank white page. Obviously it doesn't work this way.

So, is there any other way to implement ColotPicker in a API v4.12 project?
