The biggest thing I've learned in making Tamagui is that the ideal setup is not to really have specific colors at all (unless you really really are just doing a one-off single color thing), but instead to let themes handle this (essentially a classname that changes out a set of CSS variables).

Then you can do things like `color1` (or `primary1` or `secondary2`) etc, keeping them generic. With this setup you can then re-theme any area instantly, no dark-x or light-x, no green-x. You can inverse an area to be light on dark, you can change the color out if need be.

We even go one step further (as an optional feature) where you can avoid the `color1` for many cases and instead use `color`, `colorHover` etc, which allows for having themes that change contrast or the strength of their various alternate states, but that's another story.

The site itself shows off some of this, but it's really quite nice. Now your "Notice" box can be alert style, or success style, with just a single `<Theme name="alert">`.
