Hello! First, I really like the themes and Aubergine would be my favorite light theme -- except for one issue. In a text view, such as Copilot, inline code is rendered in a colour that's not possible to read against the background.
In this theme, code editors have a light background while the rest of the UI has a dark background. So code text is dark, while normal text is light. (I suspect most VSC themes don't have this difficulty.) This means that the result of inline code in a text view, presumably Markdown inline code, needs to have a different colour than normal code.
