Should secondary (help) buttons be a different colour?

I'm creating a web application that includes quite a lot of help buttons due to the complexity, initially we only had two colours for CTA buttons, primary and secondary, neither of the buttons in this example is primary.

Is it poor practise/confusing to have the help buttons the same colour as the users menu for their actions?

Or are they all considered secondary actions and it works just fine as the icon is different?

Thanks.
