G12 Sea Green is a cool green Copic Marker which resembles highly diluted Phthalo Green Blue-Shade watercolor. A highly unstable ink mixture, G12 can damage itself during layering. G12 is only available in Copic Sketch and Classic marker styles.
Every Copic Marker has unique characteristics based on its unique ink formula.
Knowing how a color behaves will help you blend effectively and make art with confidence.
G12 Sea Green
Let’s take a closer look at this Copic Marker and its ink characteristics.
Temperature: A cool green
Resemblance: highly diluted Phthalo Green Blue-Shade watercolor.
Actual Value: N2
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: Yes. The colored plastic on the Sketch cap matches 1 layer of G12 ink.
Buildup: Layers well but looks oily at 2 coats. The oily sheen looks smoother by 4 layers.
Shattering: Shatters into green with gray and yellow leakage.
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: G12 mildly stains the paper.
Lift: G12 lifts moderately well, leaving behind slightly blue paper.
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: G12 faded slightly during testing, about 5%. We would expect this to continue under extended testing.
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: G12 sits at the light end of the G-Teen family. The markers in this family all look to be related to Viridian
Family Members: G12, G14, G16, G17, G19
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 pale red-violet like RV11
Underpaint: We suggest BV0000
This is simply one suggestion. Many possible colors exist. Test to find a color that pleases you.
Pushing Pencil: Prismacolor 1026 Greyed Lavender with very light pressure works well.
VanillaArts.com (our sister site) teaches a Push & Pull technique for dimensional coloring. This is simply one suggestion. Many possible colors exist. Test to find a color that pleases you.
