YG91 is a pale murky yellow green Copic Marker which mimics diluted Chromium Green watercolor. It’s a strange color which most people will rarely use on it’s own. YG91 is available in Copic Sketch, Ciao, 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.
YG91 Putty
Let’s take a closer look at this Copic Marker and its ink characteristics.
Temperature: A watery, murky yellow green.
Resemblance: Highly diluted Chromium Green watercolor.
Actual Value: N3
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 closely resembles this ink color.
Buildup: YG91 layers beautifully.
Shattering: Shatters into green with gold seeping out at the margins.
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: YG91 is mildly staining.
Lift: This color lifts a bit. Minor errors can be corrected but the paper will never be white-white again.
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: ODD FADE. The green colorant in this ink blend faded but the golden color did not. So this color didn’t fade, it yellowed.
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: YG91 is the lightest in the YG90 series and is a highly diluted version of YG99.
Family Members: YG91, YG93, YG95, YG97, YG99
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 periwinkle that leans more towards violet than blue. If Copic were to create a BV32 or 33, I’d suggest it as a complement.
Underpaint: BV31 makes a lovely desaturation for YG91.
This is simply one suggestion. Many possible colors exist. Test to find a color that pleases you.
Pushing Pencil: Prismacolor 1097 Moss Green looks beautiful over YG91.
