Visual Studio colour setting for std::string and other user types

Question

Using Visual Studio 2022 v17.12.1 with the "Dark" colour scheme (set at Tools > Options > Environment > General > Color Theme).

I've set up various colours in Tools > Options > Environment > Fonts and Colors. These generally work well (see image below):

• if and for are purple using the C++ Keyword - Control colour setting
• void and int are blue (unsure which colour setting this uses)
• 5 is red using the Number colour setting
• string literals are orange using the String colour setting

Currently Visual Studio uses the Plain Text colour setting for std::string ("param2" in my example above, circled in bright orange), but also for other user types like std::vector and MyUserType. The C++ User Types colour setting looked promising but doesn't appear to work.

My question is whether VS can be configured to give colour to user types such as std::vector or MyUserType. This should be distinct from Plain Text.

Update

Based on the answer from @RemyLebeau, VS 2022 v17.12.1 may not have a working colour setting for C++ user types (or at least the colour rendering engine is not identifying these elements correctly).

After further experimentation, I note that the Type and Method colour settings are also not working as expected (at least in C/C++ files). All types and methods are using the Plain Text colour setting.

Seems likely that the VS colour rendering engine is not working correctly.

std::string is not a keyword in the C++ language. It is a user-defined class (implemented by the compiler vendor). That is why it doesn't get colored differently than other user-defined code elements. And no, you can't instruct VS to color std::string as a language item, because it is not one.
