It appears your fish has grown a bit and it wouldn't surprise me that the color change could be due to either water temp changes or color feed. If you do a Google search for "kin ki matsuba" you'll see pics of fish with both colors incorporated together. The word Kin refers to gold metallic and the word Gin would refer to silver metallic Ki is the color yellow and hi/beni/aka represent red/orange color. A standard, non-metallic matsuba would be an aka matsuba or ki matsuba for example. If they are metallic, the generalization would fall under the yellow/orange or combo thereof, or Gin for white base color. I've seen these varieties change rather quickly and most of my experience would be that it is environment/temperature based.
