Blue Nebula

Dark opaque navy blue that is stable and easy to work in all applications; use an oxidizing flame to minimize cobalt reduction, and holds up well when thinned.

Outcomes

• Dark opaque navy blue; consistent color with no striking required flame: OxidizingBlueIndigo
  Work in an oxidizing flame to minimize cobalt reduction. Holds up well when thinned.
• Slightly reduced navy blue if flame is not oxidizing enough; cobalt reduction can shift the tone flame: ReducingBlueIndigo
  A reducing flame causes cobalt reduction in the color, which can subtly alter the hue. Avoid reduction for truest navy result.
