Currently, the MediaWiki extension WikimediaBadges uses the same image for good and recommended articles. However, there is an image that is made for recommended articles: https://commons.wikimedia.org/wiki/File:Rekommenderad_gr%C3%B6n.svg

I suggest that the extension is updated so that good articles keep using badge-silver-star.png and that recommended articles start using Rekommenderad_grön.svg. The images are located at https://phabricator.wikimedia.org/diffusion/EWMB/browse/master/resources/images/ and the CSS is in https://phabricator.wikimedia.org/diffusion/EWMB/browse/master/resources/skins/
