Cobalt Blue
Cobalt Blue is a key colour in my plein air palette, especially for coastal light. It gives a cleaner, softer blue than Ultramarine and helps me keep skies feeling airy rather than heavy.
You'll be taken to Amazon to complete your purchase.
Pros
- +Clean, natural-looking blue for skies and distance
- +Mixes beautifully with earth colours for greys
Cons
- -Less granulating punch than Ultramarine in some mixes
What James Potter says
“So, cobalt blue largely and just really just try and get the shapes but trying to be so bold”
