Color, Tone & Optical Behavior

• Base hue / description: Sailor describes 173 Yellow as a “medium shade of peachy orange with sheening yellow undertones.”

• Goulet Pens calls it a “light orange fountain pen ink” in their listing.

• It tends to sit in the range between soft peach / coral and pale orange, with visible shading.

• In swatch tests (e.g. by Mountain of Ink), 173 shows a wide shading range, from pale orange to deeper salmon / coral tones with yellow undertones.

• When diluted or in lighter strokes, it may appear more pastel or softly tinted; in heavier strokes, the deeper tones and undertones show more strongly.

• Because it is relatively light in saturation, its visibility in fine nibs or on less receptive paper may be limited. 

• It does not include shimmer or glitter particles — the visual interest comes from shading and subtle hue variation.

Performance, Behavior & Usage Notes

• Flow & lubrication: The ink is described as “smooth flowing,” safe for fountain pens, and easy to rinse out.

• Start / reliability: No major reports of skipping or hard starts in official specs.

• Drying time: In swatch tests, Sailor 173 took about 15 seconds to dry on fountain?pen?friendly papers in one blogger’s test. 

• Feathering / bleed / show-through:
   - On good paper, feathering is minimal; show-through is moderate given its light color. 
   - On more absorbent or lower quality paper, the paleness may suffer and legibility can drop. 

• Water resistance: The ink is not water?resistant — exposure to water will cause significant wash / fading. 

• Ease of cleaning: Because it’s a dye ink without particulate additives, users report clean flushing and no heavy residue buildup. 

• User impressions:
   - Some users note that 173 is “undersaturated,” sometimes barely visible in fine or dry nibs. 
   - Others appreciate its shading and soft warmth, comparing it to coral or salmon hues. 

Ideal Use Cases & Recommendations

• Best suited for medium to broad nibs or wetter pens to bring out its shading and depth.

• Use on high-quality, fountain-pen-friendly paper (Tomoe River, Rhodia, etc.) to preserve subtle hues and prevent absorption.

• Because it is relatively light, it may be more suitable for artistic, decorative, or accent writing than for dense block text.

• Pair with complementary inks (for layering, outlining, or contrast) in art or calligraphy use.

• As part of the Ink Studio line, 173 offers a gentle, expressive coral / peach accent in any ink collection.
