In this video I’m testing out ARRTX’s Oros alcohol markers in the 90-color set, and I’m doing it the way I actually use markers: swatches first, then a little demo so we can see how they behave on paper. I go through the color range, talk about how the set is organized, and point out the kinds of shades I personally look for when I’m building a palette (good neutrals, usable skin-ish tones, and enough variety to make mixing-by-layering feel fun instead of frustrating). I also focus on the practical stuff that matters in real life: how the markers feel in the hand, how consistent the ink looks across the set, and what you can expect when you start layering for gradients and shadows. If you’re coming from watercolor like me, I share what feels familiar (that “value building” mindset) and what feels different (how fast alcohol ink moves and how it can bloom if you overwork it). By the end, you’ll know whether the Oros 90 set makes sense as a starter set, a gift, or an add-on if you already have markers and just want more color options.
