To change color of PNG image via CSS, we use the filter
property.
For instance, we write
<img src="https://picsum.photos/30/30" />
to add the img element.
Then we write
img {
filter: invert(48%) sepia(13%) saturate(3207%) hue-rotate(130deg)
brightness(95%) contrast(80%);
}
to set the filter property to add the filters we want to the image.
We set the sepai tone, invert the colors, set the bright and contrast, and rotate the hue.
