macOS NSButton Content Filter

[abcdefg12345]

Can someone please help me set content filter on objects such as NSbutton using swift, I'm trying to set content filter false colour but its not putting the colour I want it to use instead its using the default colours.

not sure what im doing wrong

if let myFilter = CIFilter(name: "CIFalseColor") {
            myFilter.name = "myFilter"
            layer.backgroundFilters = [myFilter]
            layer.setValue(NSColor.black, forKeyPath: "contentFilters.myFilter.inputColor1")
            layer.setValue(NSColor.white, forKeyPath: "contentFilters.myFilter.inputColor2")
            myButton.contentFilters = [myFilter]
        }

managed to get it working:

if let falseColor = CIFilter(name: "CIFalseColor",
                                     withInputParameters:["inputColor0" : color1,
                                                          "inputColor1" : color2
            ]) {
            myButton.contentFilters = [falseColor]
        }
