In this video I’m testing ShinHan Professional Designers Gouache and really digging into how it behaves in a real palette and on paper. I swatch the colors, talk through the color chart and the manufacturer lightfast ratings, and I show you what happens when the paint sits—because yes, I did run into binder separation and I want you to know what that looks like and whether it’s a dealbreaker. I also compare it to other gouache I’ve used and to ShinHan PASS, which is that watercolor/gouache hybrid that behaves a little differently depending on how much water you add. Along the way I do some simple demo paintings so you can see coverage, reactivation, and how easily the paint layers. I’m also sharing the practical stuff I know you’re going to ask about: what paper I used (including toned mixed media paper), what palettes I mixed on, and the brushes I grabbed for the demos. If you want the nerdy details—my written notes, the swatch images, and the color chart info—I linked my full written review so you can zoom in and compare everything side-by-side before you buy.
