Is there a way to adjust the saturation and desaturation of an image using CSS?

Issue Update

After further testing, I have discovered that the desaturation effect is only functioning properly in Chrome. How can I adjust it to work in other browsers such as FF and IE? (Title modified)

Currently, I am working on turning a color image into greyscale based on the suggestions provided here: Convert an image to grayscale in HTML/CSS

The conversion works perfectly in Chrome using this fiddle link: http://jsfiddle.net/7mNEC/

<img src="https://imagizer.imageshack.us/v2/350x496q90/822/z7ds.jpg" />

// CSSS
img {
    filter:         url(~"data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'matrix\' values=\'0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0 0 0 1 0\'/></filter></svg>#grayscale");
    -webkit-filter: grayscale(100%);
    -moz-filter:    grayscale(100%);
    -ms-filter:     grayscale(100%);
    -o-filter:      grayscale(100%);
    filter: gray; 
}

img:hover {
    filter: none;
    cursor: pointer;
}

However, I am struggling to remove the desaturation effect, for example during mouse over.

Are there any suggestions on how to correct this issue?

Answer №1

To achieve the desired effect, simply invert the grayscale for each CSS property specific to different browsers:

img:hover {
    filter: none;
    -webkit-filter: grayscale(0%);
    -moz-filter:    grayscale(0%);
    -ms-filter:     grayscale(0%);
    -o-filter:      grayscale(0%);
    cursor: pointer;
}

Answer №2

When discussing the concept of saturation, it may be more appropriate to consider using the saturate() filter. This particular filter allows for the enhancement of colors beyond 100% saturation:

img {
    filter: saturate(0%);
}
img:hover {
    filter: saturate(300%);
}

For a live demonstration, check out this JS Fiddle link.

Answer №3

To enhance the visual appeal, consider incorporating a transition effect like this:

  section {
    background-color: none;
    -webkit-transition: background-color 0.5s ease;
    -moz-transition:    background-color 0.5s ease;
    -ms-transition:     background-color 0.5s ease;
    -o-transition:      background-color 0.5s ease;
    cursor: pointer;
  }
  section:hover {
    background-color: #f1f1f1;
  }
