The Grumbacher Academy Watercolor Paint in Prussian Blue has a reputation for being a good pick if you're into the classic feel of watercolors without the fuss of being water-resistant.
According to the manufacturer's description, it's not waterproof, meaning it can easily be reactivated with water even after it has dried. This is pretty standard for traditional watercolors and can be great for techniques that involve a lot of layering and blending.
From what we've found, a lot of artists really like this aspect, especially when blending is a key part of their projects. The Prussian Blue shade, in particular, is known for its vibrant and deep blue color with a hint of green. It maintains its brightness even when you thin it out, so you've got a lot of flexibility with how you use it to get the look you want.
Just keep in mind, if you're working on something that might come into contact with water or that you want to last a long time, the lack of water resistance could be a bit of an issue. In that case, you might want to think about sealing your piece with a fixative spray after you're done to protect it from moisture.
If you need something that's water-resistant right off the bat, you might want to check out other options, like acrylic paints, since they're naturally more durable once they dry.
So, while it's not waterproof, Grumbacher's Prussian Blue is still a favorite for its vibrant color and how nicely it blends, based on what we've seen. It's a great choice if you love working with watercolors and want a color that's both vibrant and flexible.
If you're into using watercolor for expressive and layered art, this could be a solid option to have in your collection.
