To Holo, Or Not To Holo? Not Really A Question!

I have had some stunning holo pigment for quite a while now but when I asked my lovely Instagram followers if they wanted holos or thermals first they came back with a definite longing for thermals. So that is what they got! But I am now looking to do a holo collection soon. I want a collection of 4, maybe a red and a teal but what colours do you want to see?
