When it comes to yellow inks, I can't say I have much experience. It's not a color that I've been attracted to so far in my ink journey, but it doesn't mean I have anything against it, either. So, when I received a bottle of Platinum Citrus Black to try out, I was intrigued. The color of the ink that's visible through the bottle is very light and mostly transparent. I didn't expect this ink to surprise me as much as it did.
Upon inking up a pen and taking it to paper, the light, highlighter yellow ink was barely visible as I wrote. My impression was, "this is a useless color," but that's when things started to change. I hadn't researched the ink before trying it, and I discovered very quickly that Citrus Black is an iron gall ink that Platinum offers. To my surprise and delight, I watched the highlighter yellow ink transform into a deeper yellow with green tones, followed by an even deeper green/yellow that looked closer to olive. Needless to say, my initial impression was blown away.
