title: How can I disable the color of an image using css?
body: <p>This is a small question. If you go to www.thumbtack.com/jobs, and go below to their sponsors. you can see that at first you cant see the color in the names of the sponsors but when you hover over them you can see the colors appear. Can someone tell me how to do this. I am not really sure what to search on google(like what keywords to use for it). I have tried to use the inspect element but couldn't figure out how there are doing it. Any help will be greatly appreciated.</p>
