Unatural colour mapping

[rzjnzk]

I have noticed an issue with the colour mapping in the terminal. A colour that usually should be cyan on a regular terminal appears yellow in the terminal-tab when 'Match Theme' is checked. I assume this is the case with other colours. I would like to see a better rough approximation of colours, for example, cyan corresponding to the closest blue colour. If this is not possible for all colours, I would like to see a customization option per-colour that overrides the syntax-theme dictated colours that users can customize to their preferences. Syntax theme dependant colour should only be optionally overridden, and certainly remain a feature.
