If you have ever tried coloring a full character illustration with traditional paint pens, you know how tricky it can be. Most acrylic markers dry quickly with chalky, hard borders that refuse to mix.
Trying to shade a face or create a smooth color transition often feels like a wrestling match against the clock.
Ohuhu recently expanded their traditional art line with a new massive 72-marker option: the Ohuhu Hilo Blending Acrylic Markers!
I also received the Ohuhu Kahuku Acrylic Markers, to thoroughly test out and compare.
I received both 72 packs in my studio, swatched them out, and put them through real drawing tests.
Today, we are looking at how both sets behave on paper, testing their opacity, drying speeds, nib durability, and blending.

Friends at Ohuhu sent this; still my honest take, enjoy!
Ohuhu Hilo Blending Acrylic Markers (72 Pack)
The Hilo series was specifically created to solve the biggest issue artists face with paint pens: achieving smooth, natural gradients without harsh edges.
1. Curated Color System and High Saturation
When you open the 72 pack, the first thing you notice is how the palette is organized.
The markers are arranged by color families and tonal gradients, stepping cleanly from pale tints to deep shadow tones.
This makes picking your base tone, mid-tone, and core shadow straightforward. The ink formula is rich and vibrant, laying down punchy, saturated pigment on the first pass without needing multiple watery coats.
2. The Blending Test: How Smooth Is It?
This is where the Hilo markers stand out. Standard paint markers dry almost instantly into a plastic film, meaning overlapping colors simply sit on top of each other with a distinct line.
The Hilo formula has a slightly longer open working time.
When you lay down a mid-tone and immediately work a lighter shade into the wet edge, the pigments merge smoothly.
The finished effect looks much closer to traditional acrylic gouache or a digital brush gradient than a typical stiff paint pen.
3. Brush Tip Control and Paper Durability
Instead of a stiff bullet nib, Hilo markers use a flexible, durable brush tip. The nib glides across paper fibers smoothly.
When you do multiple passes to blend colors together, hard marker nibs can scrape paper into little pills.
The Hilo brush tip is gentle on paper surfaces and holds its shape well, giving you fine line control on the tip and broad coverage when pressed flat.
4. Opacity and Layering
Because this is genuine acrylic paint, it dries completely opaque and matte.
Once your base layer sets, you can add bright highlights, patterns, or white details over dark backgrounds. It also makes fixing drawing mistakes simple, since a fresh coat cleanly hides what is underneath.

Ohuhu Kahuku Acrylic Markers (72 Pack)
Along with the Hilo markers, I also tested the 72 pack of Ohuhu Kahuku acrylic markers. While both belong to the Ohuhu paint marker family, they have distinct personalities on paper.
1. Soft Palette and Fast Drying Time
The Kahuku set features a slightly softer, less saturated color range. The tones have a gentle, pastel quality that looks lovely for cozy illustrations and sketchbook spreads.
They also dry slightly faster than the Hilo markers. The paint sets on the paper within seconds of application.
2. Layering and Blending Performance
Because the Kahuku ink dries so rapidly, wet-on-wet blending is difficult. When you try to feather two shades together, you will almost always see a visible line dividing the colors.
This is not necessarily a negative if you enjoy clean comic flats, bold pop art graphics, or decorative lettering.
However, if your goal is soft skin shading or seamless color transitions, the Kahuku markers are not built for that style.

Ohuhu Hilo vs. Kahuku: Direct Comparison
Here is how both sets compare side-by-side:
- Color Saturation: Hilo gives you bold, punchy, vibrant tones. Kahuku offers softer, lighter, and more muted colors.
- Blendability: Hilo blends smoothly with painterly transitions. Kahuku dries with crisp, defined boundaries between shades.
- Drying Speed: Kahuku sets almost instantly. Hilo dries fast, but leaves just enough wet working time to mix colors on the page.
- Best Art Styles: Hilo works best for character illustrations, soft shading, and painterly artwork. Kahuku is ideal for flat color fills, graphic outlines, poster design, and journaling.
Tips for Getting the Best Results on Paper
No matter which set you pick, working with acrylic markers requires a slightly different approach than alcohol pens:
- Choose Heavyweight Paper: Water-based acrylic paint will buckle thin sketchbook paper. Use mixed media paper (at least 200 GSM) or dedicated marker books. You can check our favorite sketchbooks for artists or read our hands-on Ohuhu marker pad review for great options.
- Work in Small Areas: When blending with Hilo markers, color one small section at a time. Lay down your dark shade, grab your lighter tone immediately, and work the brush tip along the edge before the paint dries.
- Let Underlayers Cure: If you want sharp details or white gel pen highlights, wait until your base acrylic layer is completely dry to the touch to prevent muddy colors.
- Build Harmonious Palettes: Because acrylic ink is opaque, balancing warm and cool shades makes your characters pop. For a refresher on color harmony, take a look at our practical guide to color in art.

Frequently Asked Questions
Can you blend Ohuhu acrylic paint markers?
Yes, you can blend the Ohuhu acrylic paint markers because its ink formula and brush tips are designed specifically for wet-on-wet color transitions. To get the smoothest gradients, work in small sections and blend while the paint is still wet on the paper.
What is the main difference between Ohuhu Hilo and Kahuku markers?
Ohuhu Hilo markers offer vibrant colors with flexible brush tips designed for smooth blending, while Kahuku markers dry faster with softer saturation for flat, graphic coloring. Hilo creates painterly gradients, whereas Kahuku leaves distinct dividing edges between overlapping colors.
Do Ohuhu acrylic markers bleed through sketchbook paper?
No, Ohuhu acrylic paint markers do not typically bleed through paper because water-based acrylic sits on the surface rather than soaking through like alcohol markers. However, using paper under 200 GSM can cause surface warping or pilling during heavy layering.
Can you layer light acrylic markers over dark colors?
Yes, Ohuhu acrylic markers dry to a fully opaque finish, allowing you to add light highlights and white details directly over dark layers. Always let your bottom layer dry completely before painting over it so the colors stay clean.
