Holbein Marine Blue Review
Holbein Marine Blue is one of those colors that makes me want to wake up and paint.
Seriously.
Most paints eventually end up in one of two categories:
- Colors I use all the time.
- Colors I occasionally rediscover while wondering why I spent money on them in the first place.
Marine Blue belongs in the first category.
This is a rich blue-green color with enough depth and personality to immediately grab your attention. Straight out of the tube, it is very dark and intense. Diluted, it produces beautiful blue-green washes that work wonderfully in skies, oceans, shadows, and atmospheric passages.
But none of those are the reason I keep reaching for it.
The real magic is the blossoming.
Wow.
If you’ve watched many of my videos, you already know I have a slight obsession with watercolor blooms, backruns, blossoms, happy accidents, and other events that make watercolor both wonderful and occasionally infuriating.
Marine Blue is one of the best blossoming colors I’ve tested.
Put some color down on wet or dry paper. Wait until the surface reaches that magical stage where it still looks wet but is no longer swimming in water. Lay the paper flat. Then drop a little clean water into the wash.
And watch.
The pigment explodes outward into beautiful organic shapes that almost seem to paint themselves.
Clouds.
Trees.
Atmospheric textures.
Ocean spray.
Abstract effects.
All achievable simply by letting the paint do what it wants to do.
This color reminds me why watercolor is more fun than acrylic.
The paint is made from a combination of Phthalo Blue and Phthalo Green, which explains much of its behavior. Both pigments are powerful staining colors. Once Marine Blue settles into the paper, it is not especially interested in leaving.
Lifting?
Good luck.
This is not a color you choose because you plan on removing it later.
This is a color you choose because you plan on moving it around while it’s wet.
And fortunately, it moves beautifully.
Marine Blue also produces smooth graduated washes with surprisingly little streaking. Considering how strong these pigments are, it behaves remarkably well when transitioning from dark passages into lighter areas.
Granulation?
Moderate.
Not enough to qualify as a super granulator, but enough texture to keep things visually interesting. The combination of slight granulation and dramatic blossoming creates some beautiful surface effects.
Mixing?
This color loves yellow.
Add a warm or cool yellow and you’ll get brilliant greens that practically glow.
Reds, however, are another story.
Unless your goal is a dark neutral or shadow mixture, Marine Blue and red generally don’t become best friends. Most combinations head quickly toward muted darks and grays.
Which is useful.
Just not particularly exciting.
