Today’s Diamine Inkvent color is Cardinal. This is a lovely standard medium bright red ink. Here is T’s inky swatch. This appears to be a bold vermilion red color and not much else. Thank you T for taking the time to create and share your swatches with me.

It was fairly easy for me to find similar red colors from my collection. Here are my top matches.

An angled view of my swatches. Red Robin and Red Candy have a bit more personality and shows some green sheen around the edges.

Since I have a few bottles of red ink, I will not be adding this one to my wish list.
