Trying to Create and Set Color Attribute of Point via Python Component

I am having some trouble modifying attributes on a point object from the python editor. All the back and forth between rhinoscript and rhino common has me a little lost I think. The following code produced an error when it gets to the 'ObjectColor':

"Runtime error (ArgumentTypeException): expected RhinoDoc, got GrasshopperDocument"

import rhinoscriptsyntax as rs
import Rhino.Geometry as rg

def ptGrid():
#define output grid as a list
gridDimX = x
  gridDimY = x

  #loop to define X limits
  for i in range(gridDimX):
      #loop to define Y limits
      for j in range(gridDimY):

#Create a point at i, j

gridPt = rs.AddPoint( (i,j,0) )

rs.ObjectColor(gridPt, [0,0,0])

#Append Point to Output
zero.append(gridPt)

Thanks in advance if you can steer me in the right direction!

Hi Tyler Crain

The rs.ObjectColor () function can not be used in Grasshopper,If you want to call the rs.ObjectColor () function in GhPython,You have to let ghdoc = Rhinodoc like this "sc.doc = rr.ActiveDoc".

If you just want to show the color of the point,You can use the AddPoint (Point3d, Color) method under the Rhino.Display.CustomDisplay (True) instance,like this.
