Grout variety
I am a novice mosaic artist to say the least...novice might even be higher than my current abilities and knowledge. But I've been lurking in this sub because I love the art form and want to give it a shot im the future.
That being said, I'm wondering about the variety of grout. It seems like I see the same (maybe most popular/effective?) Colors posted mostly - black, Grey, other flat colors.
Are there iridescent grouts? Glittery grouts? Color gradient grouts?
I understand that the limited and darker color choices are most likely the best background color to tie the piece together, which is ultimately the focus and not the grout itself, but I'm just wondering (or maybe waiting to see) if artists on here ever use less common grouts?
Imagine a mosaic of a flowing river with light reflecting grout or a beetle mosaic with an iridescent grout...does it even exist?
