import bpy

# 1
MAT_NAME = "Material_Name"
# 2
AOV_NAME = "AOV_Name"
# 4
NODE_NAME = "AOV Output"

for a in bpy.data.materials:
    if a.name == MAT_NAME:
        for n in a.node_tree.nodes:
            print(n.name)
            # 2
            if n.name == AOV_NAME:
                # 3
                print(n.color)
                # 1 + 4
                print(bpy.data.materials[str(MAT_NAME)].node_tree.nodes[str(NODE_NAME)].inputs[1].default_value)

You can get the currently active AOV with bpy.types.ViewLayer.active_aov, all AOVs with bpy.types.ViewLayer.aovs, and access AOV attributes/methods using bpy.types.AOV.

import bpy

for a in bpy.context.view_layer.aovs:
    print("All View Layer AOVs: " + a.name)
