Cambiar el color del degradado según la selección del usuario

Estoy tratando de cambiar el color de un degradado según la selección del usuario, tengo todo funcionando pero no sé cómo cambiar el degradado usando el formato que tengo. ( change.style.background = "linear-gradient(90deg, color1, red)"; ).

 const len = document.querySelectorAll("input").length; let change = document.querySelector(".body"); for (let x = 0; x < len; x++) { document.querySelectorAll("input")[x].addEventListener("input", function() { let color1 = this.value; if (this.getAttribute("name")==="color1") { change.style.background = "linear-gradient(90deg, color1, red)"; } }); }
 .body{ background:linear-gradient(90deg, blue, red); }
 <!DOCTYPE html> <html lang="en" dir="ltr"> <head> <meta charset="utf-8"> <title></title> </head> <body class="body"> <h1>Background Generator</h1> <input type="color" name="color1" value="#996DAD"> <input type="color" name="color2" value="#23AD23"> </body> </html>

Puede usar literales de plantilla para que los valores del selector de color se inserten dinámicamente en el CSS.

Además, en lugar de recorrer todos los elementos y luego configurar controladores de eventos para cada uno de los elementos de input , puede aprovechar la "delegación de eventos" y configurar solo un controlador de eventos.

 const picker1 = document.querySelector("input[name='color1']"); const picker2 = document.querySelector("input[name='color2']"); // No need to loop over all the input elements and set up an event // handler for each. Just set up one event handler at a common ancestor // of the elements you care about and let the event bubble up to be // handled there document.addEventListener("input", function(event){ // Now test to see if the event was triggered by an element you // wish to handle if(event.target.classList.contains("colorPicker")){ // Use template literals to insert JS values into a string: document.body.style.background = `linear-gradient(90deg, ${picker1.value}, ${picker2.value})`; } });
 .body{ background:linear-gradient(90deg, blue, red); }
 <!DOCTYPE html> <html lang="en" dir="ltr"> <head> <meta charset="utf-8"> <title></title> <link rel="stylesheet" href="styles.css"> </head> <body class="body"> <h1>Background Generator</h1> <input type="color" name="color1" value="#996DAD" class="colorPicker"> <input type="color" name="color2" value="#23AD23" class="colorPicker"> <script src="script.js" charset="utf-8"></script> </body> </html>
