Bagaimanakah saya boleh mencipta imej skala kelabu yang mewarna semula pada tetikus menggunakan CSS?

<code class="css">img.grayscale {
  filter: url("data:image/svg+xml;utf8,..."); /* Firefox 3.5+ */
  filter: gray; /* IE6-9 */
  -webkit-filter: grayscale(100%); /* Chrome 19+ & Safari 6+ */
}

img.grayscale:hover {
  filter: none;
  -webkit-filter: grayscale(0%);
}</code>

<code class="css">img.grayscale {
  -webkit-filter: grayscale(100%);
}</code>

<code class="html"><svg xmlns="http://www.w3.org/2000/svg" id="svgroot" viewBox="0 0 400 377" width="400" height="377">
  ...
  <image filter="url(&quot;#filtersPicture&quot;)" ... />
   </svg></code>

<code class="css">img.grayscale {
  filter: grayscale(100%);
}</code>

<code class="js">const grayscaleImages = document.querySelectorAll('.grayscale');

grayscaleImages.forEach(image => {
  image.addEventListener('mouseover', () => {
    image.src = 'path/to/color_image.jpg';
  });

  image.addEventListener('mouseout', () => {
    image.src = 'path/to/grayscale_image.jpg';
  });
});</code>
