Use with TileLayer.fallback ?

[vincedchart]

I'd like to use this great, interesting plugin in combination with another one: Leaflet.TileLayer.Fallback

[https://github.com/ghybs/Leaflet.TileLayer.Fallback)]

This would allow me to save resources when I want a color info.

While this has been ok, and while I'm noting that 2 colorpickers running in the same time do work,

var colorpicker = L.tileLayer.wms
.colorPicker("https://service.com/geoserver/gwc/service/wms?", {
  layers: colorpicktoask,
  maxZoom: 18,
  format: 'image/png',
  opacity: .0,
})
.addTo(map);

the fallback plugin would'nt work instead,

var colorpicker2 = L.tileLayer.fallback
.colorPicker("https://service.com/geoserver/ows?", {
  layers: colorpicktoask2,
  minNativeZoom: 4,
    maxNativeZoom: 8,
  maxZoom: 18,
  format: 'image/png',
  //opacity: .0,
  //attribution:"<a href='https://pacific-data.sprep.org/dataset/landsat-8-satellite-imagery-collection-1-papua-new-guinea'>SPREP</a>",
})
.addTo(map);

with the error: Uncaught TypeError: L.tileLayer.fallback.colorPicker is not a function

So I'll be eager for your help on this exciting function too :)
