I've been having a great time experimenting with the new FIMO Professional clay with the True Color System. The colors are phenomenal and mix easily and beautifully. I've been playing around with the formulas in the True Color mixing chart (seen below - click on image to link to a pdf version of the full chart). It comes in 24 colors (including six in the True Color system). In addition, there is also a companion line of FIMO Doll Art flesh tones for doll making and sculpting. There is also a set of available of the six True Color clays that correspond with the 170 color recipes. Even though it's softer, I didn't find it to become sticky. It offers the matte consistency I also enjoy with the FIMO Soft line. The colors remained true during baking which is another plus for me.
I find it much easier to condition than FIMO Classic but it still offers the same superior finished strength and flexibility (in thinner pieces) as the original FIMO clay. In addition to the seen above, I've been making several new pieces with the clay that can been seen under the "FIMO Professional" Gallery in this blog. I intend to add new images as more pieces are created. I can't get enough of this stuff!
