[SOLVED] How can change color for a Area lamp? (Cycles)

How can change color for a lamp?

I try this:

>>> bpy.data.node_groups[“Shader Nodetree”].nodes[“Emission”].inputs[0].default_value = (1, 0, 0.00657589, 1)

But get error:

Traceback (most recent call last):
File “<blender_console>”, line 1, in <module>
KeyError: ‘bpy_prop_collection[key]: key “Shader Nodetree” not found’

Thanks.

SOLVED:

bpy.context.selected_objects[0].data.node_tree.nodes[‘Emission’].inputs[‘Color’].default_value = [1, 0, 0.00657589, 1]
