Enhancing The Modal Bar

I have installed kickstarter’s init.lua, and I really love NVIM.

However, I need to tweak something. I’d like the bar that displays modal changes (visual/normal/insert)
to be more pronounced. Perhaps longer, and certainly jazzier in colour.

So generally I like muted or sensible colours, but for the modal bar, I want it to be strident.

Can I modify onedark easily, or do I need to find a new theme, and if so, which one?

I think before I had Everblush.
On Kitty I use earthsong GitHub - dexpota/kitty-themes: A collection of themes for kitty terminal 😻

Am looking for something sensible, but with electric pink and blue on the modal bar, that kind of thing
