All hail the Dark Cobalt Supreme! DCS is at the very edge of the saturation threshold where it goes from distinctly cobalt to pure darkness.
Boro Batch knows that you need all different kinds of saturations of blue to round out your palette so they’ve brought you the workability of Dave’s Blues but with a much deeper saturation. Dark Cobalt Supreme has the same working properties of Dave’s Blues but just needs a bit more heat to get it moving.
