Create and draw on color layer from script

Scripting
1

I’m experimenting with drawing a color font (Option C: native Color layers) completely from a script. I’m stumbling at the point I try to set the layer to be a color layer. Here’s a skeleton version:

thisFont = Glyphs.font
selectedLayers = thisFont.selectedLayers
newGlyphNames = ("A")
Glyphs.clearLog()

# just draws a box at present
def drawGlyph(myBottomLeft, myTopRight):
	try:
		myRect = GSPath()
		myCoordinates = [[myBottomLeft[0], myBottomLeft[1]], [myTopRight[0], myBottomLeft[1]], [myTopRight[0], myTopRight[1]], [myBottomLeft[0], myTopRight[1]]]
		for thisPoint in myCoordinates:
			newNode = GSNode()
			newNode.type = GSLINE
			newNode.position = (thisPoint[0], thisPoint[1])
			myRect.nodes.append(newNode)
		myRect.closed = True
		return myRect
	except Exception as e:
		return False

def process(thisLayer):
	layerIsEmpty = (len(thisLayer.paths) == 0 and len(thisLayer.components) == 0)
	thisGlyph = thisLayer.parent
    # ?????
	thisLayer.colorObject.set()	
    # ????
	R, G, B, A = thisLayer.colorObject.colorUsingColorSpace_(NSColorSpace.genericRGBColorSpace()).getRed_green_blue_alpha_(None, None, None, None)
	thisLayer.colorObject = NSColor.colorWithDeviceRed_green_blue_alpha_(247.0 / 255.0, 74.0 / 255.0, 62.9 / 255.0, 1)
    
	thisLayer.vertWidth = 800
	bottomLeft = (0, -200) 
	topRight = (thisLayer.width, thisLayer.vertWidth) 
	layerRect = drawGlyph(bottomLeft, topRight)
	if layerRect:
		thisLayer.shapes.append(layerRect)
for glyphName in newGlyphNames:
	original = glyphName
	print(original)
	if thisFont.glyphs[original]:
		thisGlyph = Font.glyphs[glyphName]
		print(thisGlyph)
		for thisLayer in thisGlyph.layers:
			print(thisLayer)
			thisLayer.clear()
			thisGlyph = thisLayer.parent
			if thisGlyph:
				process(thisLayer)
	else:
		print("%s: not found in font." % original)
		Glyphs.showMacroWindow()

The colorObject.set function returns 'NoneType' object has no attribute 'set'…

layer.attributes[‘color’] = True
