杂色生物界，英文是Chromista，其中文名称还有假菌界（因包含"假的真菌"——卵菌）、藻菌界、原藻界、色素界、藻物界、藻界、色虫界等等，尚无统一译名。

色藻界属于真核生物域，可能是多源的. 细胞的色素体具有四层膜，含叶绿素a和叶绿素c和其他一些无色的类似物质。被认为是内共生红藻进化而来。

假菌界有三个门：

2010年, 汤玛斯·卡弗利尔-史密斯指出应把囊泡虫总门, 有孔虫界与太阳虫并入色藻界。这实际意味着把有孔虫界并入了囊泡藻界。

The Chromista are a eukaryotic supergroup, probably polyphyletic, which may be treated as a separate kingdom or included among the Protista. They include all algae whose chloroplasts contain chlorophylls a and c, as well as various colorless forms that are closely related to them. These chloroplasts are surrounded by four membranes, and are believed to have been acquired from some red algae.
