Cannot change node color in node editor

[rbrunet]

Hi all:
I am trying to change a node color with the following code

import dearpygui.dearpygui as dpg

dpg.create_context()
color = (37, 28, 138)

with dpg.theme() as theme_id:
    dpg.add_theme_color(dpg.mvNodeCol_TitleBar, color, category=dpg.mvThemeCat_Nodes)

with dpg.window(label="Node link  animation", width=400, height=400):
    with dpg.node_editor():
        with dpg.node(label="Node 1") as node1:
            dpg.bind_item_theme(node1, theme_id)

dpg.create_viewport(title='Title', width=800, height=600)
dpg.setup_dearpygui()
dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()

but I get

Exception: 
Error:     [1003]
Command:   add_theme_color
Item:      22 
Label:     
Item Type: mvAppItemType::mvThemeColor
Message:   Incompatible parent. Acceptable parents include:	mvAppItemType::mvThemeComponent
mvAppItemType::mvTemplateRegistry


The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/home/rbrunet/PycharmProjects/pythonsandbox/dear_pygui_node_color.py", line 7, in <module>
    dpg.add_theme_color(dpg.mvNodeCol_TitleBar, color, category=dpg.mvThemeCat_Nodes)
  File "/home/rbrunet/PycharmProjects/pythonsandbox/venv/lib/python3.9/site-packages/dearpygui/dearpygui.py", line 7119, in add_theme_color
    return internal_dpg.add_theme_color(target, value, label=label, user_data=user_data, use_internal_label=use_internal_label, tag=tag, parent=parent, category=category, **kwargs)
SystemError: <built-in function add_theme_color> returned a result with an error set

Any idea what could be wrong?
Any help would be appreciated!

Thanks,
Richard

I figured out my mistake. I needed to add dpg.theme_component()

import dearpygui.dearpygui as dpg

color = (255, 0, 0)

dpg.create_context()
with dpg.window(label="Node link  animation", width=400, height=400):
    with dpg.node_editor():
        with dpg.node(label="Node 1") as node1:
            with dpg.node_attribute(label="Node A1"):
                dpg.add_input_float(label="F1", width=150)
    with dpg.theme() as item_theme:
        with dpg.theme_component(dpg.mvAll):
            theme_id = dpg.add_theme_color(dpg.mvNodeCol_TitleBar, color, category=dpg.mvThemeCat_Nodes)

dpg.bind_item_theme(node1, item_theme)

dpg.create_viewport(title='Title', width=800, height=600)
dpg.setup_dearpygui()
dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()
