If you collect colors the way some people collect books, Saffron is the orange your palette has been missing. This dye-based, non-carbon ink delivers a warm, saturated orange with smooth, consistent flow in any converter-compatible fountain pen, and its water-soluble formula makes it just as useful for drawing and wet-brush work with soft brush pens or dip pens.
The 5 mL size is a natural starting point if you're new to fountain pen ink and want to try a statement color without committing to a full bottle. For those already deep in a system, a warm orange works well as an accent: underlining, color-coding, or adding contrast to a neutral-heavy setup. Non-carbon formula means less clogging and easier cleaning than carbon-based inks, so it fits into a regular rotation without added maintenance.
