How do I get the Color value from an RGB node with Python?
$begingroup$
I'm a seasoned programmer, but fairly new to blender and 3D-modeling in general. So to get an understanding of different properties I want to write python scripts to create multiple renderings with different settings of various values.
In the example below I have figured out how to change the Volume Absorption Density, ex:
bpy.data.materials['MyMaterial'].node_tree.nodes['Volume Absorption'].inputs['Density'].default_value = 100
But not the RGB-node. It seems I cant even get the current values out of it. Some things I have tried:
bpy.data.materials['MyMaterial'].node_tree.nodes['RGB'].color
bpy.data.materials['MyMaterial'].node_tree.nodes['RGB'].color.r
bpy.data.materials['MyMaterial'].node_tree.nodes['RGB'].color.outputs['Color']
How do I get and set output values of the RGB-node in py python-script?

Welcome to Blender.SE, UlfR.
Finding out a property in Blender is relatively easy. Make sure, you have python tooltips enabled (in the user preferences).
Then hover your mouse cursor over the property (in this case the color). A tooltip containing the python command will appear.
The property you seek seems to be outputs[0].default_value
.
def_rgb = bpy.data.materials['MyMaterial'].node_tree.nodes['RGB'].outputs[0].default_value
It is a bpy_prop_array
by default, so you may want to convert it to a list.
float_values = list(def_rgb)
$endgroup$
$begingroup$
Miceterminator beat me to it by 3 minutes. I will leave this answer up, as it mentions the python tooltip and his doesn't you could accept his answer as the correct one however.

my problem was that bpy.data.materials[1].node_tree.nodes['RGB'].outputs[0].default_value = (1.0,1.0,0.5,1.0) works but bpy.data.materials[1].node_tree.nodes['RGB'].outputs[0].default_value produces nothing in the Python console. Converting it to list then displayed the hidden values.

You can also access the individual values directly from thebpy_prop_array
via their indices, such asdef_rgb[0]
.
