Struct ColorPair 

pub struct ColorPair { /* private fields */ }

A foreground and a background color, one over the other, with a button that swaps them.

It holds the two colors and swaps them. Choosing a new one is up to whoever uses it, as when a click on a square opens a ColorPicker.

use ravenrs_core::Color;
use ravenrs_reactive::State;
use ravenrs_widgets::ColorPair;

let (front, back) = (State::new(Color::BLACK), State::new(Color::WHITE));
let pair = ColorPair::new(front.binding(), back.binding())
    .defaults(Color::BLACK, Color::WHITE)
    .on_foreground(|| { /* open a picker */ });
