RGB-backlight keyboard interactive context-sensitive integration with Linux environment

I would like for example when editing in VI, that my RGB keyboard would highlight shortcut keys in different colors, or when I press CTRL in gnome then pgup, pgdown, up, down, would be highlighted in red color, alt and shift green color, etc. The color of keys would depend on the current context. Is there any such project going on? Is it even possible to accomplish? Thanks.
