I’m not sure exactly. Doesn’t quite look like its starting to fade or anything so probably not a golden base. Doesn’t look very two toned yet either. Just seems to be another unique, very cool looking kamfa. It doesn’t require a label as a label is just a label. Golden base are golden base because of the fader gene. The name is made up. Dual tone or two toned is a coined term for having two different obvious and very bright colors on front end and back end with clear separation. Often yellow on the back end and a degree of red on the front. Yours look like it COULD end up being considered a two-tone with that yellowing on the back end and the pretty clear separation straight down the middle but front end color is very underdeveloped but look like it could possible develop quite a bit red. Overall color is still underdeveloped to really tell. Two early to call it a two toned but it definitely could be one. Again labels are just labels. Doesn’t really matter. Super Cool looking FH you got there in my opinion, anyway.
