Changing the Color of PNG Images using CSS Filters and SVG

In this tutorial, we will explore how to change the color of a PNG image using CSS filters and SVG. We will cover various techniques, including using the filter property in CSS, creating custom SVG filters, and utilizing online tools to generate the necessary filter code.

Introduction to CSS Filters

CSS filters are a powerful tool for applying visual effects to HTML elements, including images. The filter property allows you to apply a variety of filters, such as blur, brightness, contrast, and hue rotation, to an element. We can also use the invert, sepia, and saturate filters to change the color of an image.

Using CSS Filters to Change Image Color

To change the color of a PNG image using CSS filters, you can use the following code:

img {
  filter: invert(48%) sepia(13%) saturate(3207%) hue-rotate(130deg) brightness(95%) contrast(80%);
}

This code applies a combination of filters to the image, resulting in a color change. You can adjust the values of each filter to achieve the desired color.

Using Online Tools to Generate Filter Code

If you’re not sure what filters to use or how to combine them, you can use online tools like the CSS filter generator to generate the necessary code. These tools allow you to input your desired color and generate the corresponding filter code.

Creating Custom SVG Filters

Another way to change the color of a PNG image is by using SVG filters. You can create a custom SVG filter that multiplies the color of the source image with the color you want to change to. Here’s an example:

<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="60" height="90">
  <defs>
    <filter id="colorMask">
      <feFlood flood-color="#ff0000" result="flood" />
      <feComposite in="SourceGraphic" in2="flood" operator="arithmetic" k1="1" k2="0" k3="0" k4="0" />
    </filter>
  </defs>
  <image width="100%" height="100%" xlink:href="image.png" filter="url(#colorMask)" />
</svg>

This code creates a custom SVG filter that changes the color of the image to red.
