What is the last test?

What lines of code do you believe satisfies that test?

What debugging have you done so far?

3

test 14 fails:When your #color-input value is changed, your #color-picker-container should change its background color to reflect that value.

style={{backgroundColor: color,

4 
const { useState } = React;

export const ColorPicker = () => {
const [color,setColor]=useState('#ffffff')

function colorChange(e){
  setColor(e.target.value)

}
  return (
  <div id="color-picker-container" style={{backgroundColor: color,
    padding: '20px',
     borderRadius: '8px',
    transition: 'background-color 0.5s ease',
}}>
    <input id="color-input" type='color' onChange={colorChange} value={color} />
    <h1 style={{ color: '#333' }}>Selected color: {color}</h1>
    </div>
  )
};

new code

i removed :

padding: '20px',
     borderRadius: '8px',
    transition: 'background-color 0.5s ease',

from the style and it passed

oh, yeah, transition makes the change happen after the tests check things
