What is the lowest hanging fruit someone should build, but you haven't seen built yet? 

Would love to see the one line pitch + why it's so badly needed in your eyes.
Bonus points for pointers on how to get started building

Colors.

That's probably one of the most complex problems for a frontend engineer.
We ain't artists – but we need something to get started with.

I'm a big fan of Radix Colors myself – https://www.radix-ui.com/colors/docs/palette-composition/understanding-the-scale

It offers a range of colors with scales adapted to all UI cases – buttons, hovers, backgrounds etc.

However, I found that colors are quite "default" and often don't meet the expectations of the end product look.

But, I don't know how far ago, this grail has dropped – https://www.radix-ui.com/colors/custom.

It lets you generate the whole scale of colors and they look awesome!
I took the script from their repo and added output of HSL values so they are pluggable in shadcn – https://gist.github.com/dalechyn/2ccaf2a30f75d9dd953b67c9dbbaf64a.

Run with Bun, generate color scales with ease!

Website to generate 12 shades of any color via radix's custom color palette tool and have it ready to copy & paste into shadcn.

Radix website isn't enough as it doesn't match shadcn's color pallete (like destructive color, secondary, outline, popover, modal etc), and you have to copy&paste it one by one.
