A version of PG50, which I’ve previously spotlighted as Cobalt Turquoise! WN also has a Cobalt Teal PG50, but this one is much more tilted toward green, resulting in a granulating semi-opaque mint green.
Pigment Stats for PG50
Chemical Composition: Cobalt Titanate Green Spinel (Co)2TiO4 per ArtisCreation
Lightfastness: Excellent (I)
Toxicity: Toxic, but not water soluble, per ArtisCreation:
The pigment is not soluble in water and so probably poses little hazard in normal use.
Observations of WN Cobalt Green
Hue: A cool green similar to mid-tone Phthalo Green BS. Doesn’t get super dark, a bright bold mint to a pale pastel.
Gradient: Granulating, settling in three distinct levels (full strength, light strength, very light).
Transparency: Opaque to semi-opaque, with residue on the line (admittedly it looked more opaque when wet).
Glazing: Darker green in glaze, closer to Viridian.
Tinting Strength: Moderate to weak.
Comparison to Other Brands
Letter Sparrow – Kelly Green
Letter Sparrow’s Kelly Green is an even greener/more yellow-toned version of this color, which has the look of a platonic-ideal green. A nice opaque granulating green for foreground foliage, mixing a range of different green tones with various mixers. Quin Magenta is quite an even complement. Very nice dark green mixes with Violet Ochre, Quin Coral, and Burnt Sienna Deep.
Comparison to Other Colors
Each of these “personalities” of PG50 is somewhat similar in hue to another color. LS Kelly Green looks like Phthalo Green Yellow Shade (PG36), only it’s more opaque and granulating. WN Cobalt Green looks like midtone Phthalo Green Blue Shade (PG7), only again, more opaque and granulating. Cobalt Turquoise is pretty unique, being much bolder and greener than, say, Cerulean.
My Review of Cobalt Green
I like these colors to swatch, but I found I didn’t often reach for either of them – neither the Letter Sparrow shamrock hue or the WN mint hue. WN Cobalt Green looks bright on the sample page, but in comparison to the colors of my Neon Palette, it seemed dull. It mixes similarly, but less flexibly, compared to the brighter, stronger, and more primary Cobalt Turquoise.

One response to “Color Spotlight: Cobalt Green (PG50)”
Oh wow, I have been playing with this too (it ended up as a “tester” in my Toolkit palette) and… I just posted about how I am unimpressed by it. The mixes are so often duller than I want (or expect, based on experience with other colors of similar hue.
The Letter Sparrow color looks better, as it is at least usable on its own.
