You were told “Ohuhu is the Copic slayer! They’re like Copic Markers but better!”
Is it true?
Every Ohuhu Marker has different characteristics based upon its unique ink formula. No matter how great they say the marker is, test results do not lie.
So are Ohuhu markers as great as you’ve heard?
Let’s look at Ohuhu G7 to find out.
WARNING: Ohuhu markers have numbers on the cap but not on the body of the marker. We do not recommend coloring with both caps off due to the risk of accidentally placing the wrong caps on a marker.
Test results: Ohuhu G7 Chromium Oxide Green
REFILL WARNING! At this time, Ohuhu does not sell refills for G7. To date, you must purchase a new marker when your current marker runs dry. See Ohuhu’s current list of refills here.
Temperature: A deep green with blue undertones
Resemblance: Hooker’s Green watercolor
Actual Value: N9
Unlike Copic, Ohuhu does not measure value— this is a glaring deficiency which makes finding blending combinations harder than it has to be!
All Copics are measured on a Neutral Gray value scale. The last number on the Copic cap indicates the value. We’re using the Copic scale to measure Ohuhu until Ohuhu releases a reliable value scale.
Cap Accuracy: The plastic on an Ohuhu Honolulu G7 marker matches 2 coats of ink.
Copic Substitution: Ohuhu G7 is slightly warmer than Copic’s G29 but otherwise, they are a near match in hue and value.
Note: similar colors rarely behave the same way. From experience I can tell you that Copic G29 is a less staining marker and thus easier to blend. See the test results for Copic G29 here.
Buildup: G7 reaches a maximum value at 3-4 coats.
Overinking: We do not recommend using more than 4 coats of G7. As with most Ohuhu markers, four layers looks oversaturated and dull.
Shattering: This ink is a mixture of green and brownish-green inks. Noticeable brown ink may appear along the edges of any area corrected with a colorless blender. Use caution when correcting mistakes.
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: As with most dark colors, G7 is a staining color but this ink felt particularly stubborn.
With alcohol markers, a staining ink is generally a sign of a low quality ink. Staining inks bond to the paper fibers and are reluctant to release. Staining inks make blending harder than it has to be!
Lift: Forget about it. G7 is stubborn and stains the paper light blue. The ink itself moves very little and I think trying to make a correction with colorless blender will cause more damage than the mistake itself. See staining above, this is a sign of a low quality ink.
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: G7 faded about 15% during the test period. This is about average and comparable to most Copic markers.
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 marker art under these conditions.
Ink Color Family: The “G” in G7 indicates that this marker is part of the G Green family.
The Ohuhu numbering system is complete garbage and doesn’t always make sense. Some blue green markers are hidden in the G family but for the most part, the G family makes sense. But be warned, when it comes to other color families, you can not trust anything you read on an Ohuhu cap.
Cap Numbering: G7 has no relation in tone or color to G6 and the two makers do not blend well together. The solvent in G6 actually damaged G7 quite badly.
As stated above, the Ohuhu numbering system makes no sense. The markers are not arranged in chromatic order so you can not trust the numbers to tell you whether this marker is lighter or darker than other Ohuhu markers with similar numbers.
I’m still early in the Ohuhu testing process. I will add more info to this article as I learn more and when I spot behavioral patterns.
From what I’ve learned so far, I will not be working with Ohuhu markers and I will discourage students from using them in my classes. They’re simply not worth the frustration.
