YG45 Cobalt Green
Let’s take a closer look at this Copic Marker and its ink characteristics.
Temperature: A warm green.
Resemblance: diluted Cobalt Gold watercolor.
Actual Value: N5
All Copics are measured on a Neutral Gray value scale. The last number on the cap is supposed to indicate value but we’ve found discrepancies where the actual ink value is different than cap designation.
Cap Accuracy: The colored plastic on the Sketch cap closely matches 2 layers of YG45 ink.
Buildup: YG45 does not layer well. The ink develops oily streaks on the second layer.
WARNING: This ink is unstable. by three layers, the solvent in YG45 starts to damage itself, shattering the ink as you color. You’ll notice this self-shattering as golden bleeding around the outside edge of the area you’re coloring. At five layers, this ink mottles badly.
Shattering: Shatters into green with golden green seeping out at the margins. See warning above for YG45’s self-shattering behavior.
Chromatography testing shows this ink’s behavior when it comes in contact with #0 Colorless Blender (solvent). High shattering colors may leak unexpected color when you make corrections or attempt to blend with any color that has a high solvent to colorant ratio. Shattering is not bad, it’s just something to be aware of.
Staining: YG45 is highly staining
Lift: YG45 can be moved but not lifted. The paper is permanently stained light blue, the edges of the area exposed to colorless blender can look slightly metallic, a golden green. We do not recommend trying to lift this color due to the damage cycle colorless blender will trigger.
See staining swatch. Sample was given 6 stripes of #0 Colorless Blender, drying between each stripe. Results indicate how much lifting you can expect.
Lightfast: YG45 faded by about 5% during the testing period.
Samples were swatched on X-Press It Blending Card. 1 layer of ink was exposed to windowsill sunlight for 21 days. Approximately 10 hours of sun per day based on weather conditions. Note: we do not recommend displaying original Copic art under these conditions.
Natural Ink Family: YG45 is the darker of two markers in the YG-Forty family.
Family Members: YG41, YG45
We include this information because many Copic users never think deeper than the letter groupings (R, BV, G, etc.). Every ink has its own temperature variations and underlying flavors. Understanding what an ink looks like in its different dilutions helps when creating your own blending combinations.
Complement: A cool, medium purple-pink like V05
Underpaint: V01 desaturates YG17 with bright but natural look..
This is simply one suggestion. Many possible colors exist. Test to find a color that pleases you.
Pushing Pencil: Prismacolor 1090 Kelp Green provides a nicely desaturated push for YG41.
