Ash is the ink for Day 3 of Inkvent. It's a Standard ink. I laid it on pretty thick in this swatch, but you can see the lighter tones around the edges. It seems to have a greenish-goldish-brownish tinge to it too. I like a nice gray ink, and this is a nice gray ink.
Did you ever wonder what the difference is between "gray" and "grey"? Oh, just me?
Well, you're about to find out. Ready?
"Gray" is the American spelling and "grey" is the British spelling. To remember this distinction, think of it this way: Gray is a color; grey is a colour. Ta-da!
