Luminance by Caran d’Ache
Luminance are the most expensive pencils on this list.
They have a creamy texture to it, but on some surfaces they have a chalky feel – which is nothing I really like. But I got the tip to use the polychromos as a first layer and then work the Luminance on top.
I got my full set of Luminance right before the 2016 DRAWember challenge and had fun experimenting with them during the challenge.
