Voltage, Lightning and Outburst.
These are glassy sheer-ish jellies with gold holo glitter in various sizes. Initially, I was a tad disappointed that all of the shades had the same gold glitter, but each coloured jelly lends different multi-coloured glints as the glitter shines through - add in the holo and it's a multitude of rainbow dazzle.
Whilst I was swatching these, it dawned on me that these would be ideal candidates for layer mixing:
Voila! Two new shades. Left to right, Voltage and Outburst giving a violet; Voltage solo; Lightning solo, Lightning and Outburst together giving teal and finally Outburst solo.
As much as I like the blue and green, it was the teal that really did it for me, so that's what I went with.
One coat of Lightning (green), one of Outburst (blue) and another Lightning. Finished with Seche. On reflection I should have got the Gelous out.
