Icon Set Colors

I’m hoping someone can help me. Not sure if this is the right place for this. I downloaded the following icon set: https://elements.envato.com/12-election-and-campaign-icons-VNFD78 - the preview shows that it is orange, but when I downloaded the set, it is just black & white.

Do I need to some css to make it have color or is there something that I’m missing?



yes, you need css, ilustrator, indesing of preference, or photoshop if they are in .png
