An icon must be purchased via a NounPro subscription in order to download it in a new color.
Free account holders can unlock the color tool by upgrading to a subscription here, thenounproject.com/accounts/signup/pro/
To change an icon’s color, simply find the icon you want and select one of the preset colors options found beneath the icon. Select the dropper icon to find the perfect color or simply enter the hex value if you already have a color in mind.
Once you are happy with your color, select download, and your icon will download in the color you chose.
*Icons purchased a-la-carte or via pre-paid balance must be modified on the user's own terms.
