I'm trying to create an oojs-ui theme based off wikimediaui theme. However, currently [[ https://doc.wikimedia.org/mediawiki-core/master/php/classResourceLoaderImage.html#af175f04760e32c375950f156f0b654d6 | ResourceLoaderImage ]] generates SVGs wihout a base color. Setting defaultColor explicitly with a different color should change the color of generated SVGs even if other variants are defined. One use case of this is that it allows theme developers to reuse images from wikimediaui for use in dark themed MediaWiki skins.
Steps to reproduce if this is a bug:
