Color, Visual Behavior & Characteristics

• Color / Hue:

  • Often described as tea green brown, or a green?brown / olive olive?brown shade — that is, a blend between green and brown, evoking the color of tea leaves or brewed green tea. 

  • In some contexts, when wet it may lean more green, and after drying drift toward a brownish tone. 

• Shading / Tonal Variation:

  • Medium shading is observed — with lighter and darker passages depending on nib wetness, stroke thickness, and paper quality. 

• Sheen / Reflective Effects:

  • Occasionally, in areas of heavier saturation (inks pools, broad strokes), a subtle reddish sheen may appear. It is not a heavy or guaranteed effect, but visible under favorable conditions. 

  • It is not a shimmer ink (no glittery particles) — the visual interest comes from shading and occasional sheen, not sparkle. 

• Saturation / Depth:

  • It is a moderately saturated ink: substantial enough to show color, yet not too dark to lose nuance. 

• Water Resistance / Durability:

  • It is not marketed as water- or bleach-resistant. 

  • However, some user tests suggest that parts of the ink may resist washing somewhat (leaving a faint blue or green mark) depending on paper and exposure, though the primary colored layer is vulnerable to water. 

Performance & Writing Behavior

• Flow & Wetness:

  • Reviewers describe Rikyucha as rather wet with very good flow. 

  • Lubrication is also praised: the ink glides smoothly across paper surfaces. 

• Dry Time:

  • On a test of Clairefontaine Triomphe paper, the ink dried in ~16 seconds. 

• Start-up / Hardness:

  • No problems with hard starts, even after the pen sits uncapped briefly, were observed by reviewers. 

• Feathering / Bleed / Show-through:

  • On good paper, feathering and bleed are minimal or absent. On cheaper or highly absorbent paper, some show-through or light feathering might appear. 

• Staining & Clean-up:

  • Users report that the ink does not heavily stain pens, and it is relatively easy to clean out (no major “crud” or residual build-up) even after days of use. 

• Behavior under water / wash test:

  • In water exposure tests, the colored layer washes away, but traces of blue/green tones may remain faintly visible, suggesting some degree of partial resistance in deeper layers. 

Usage & Compatibility Notes

• Safe for all fountain pens: As a dye-based ink (non-pigmented, non-iron-gall), it is generally safe for use in fountain pens, converters, squeezable cartridges. 

• Best results in wetter pens / broader nibs: Because of its shading and sheening nuances, pens that deliver more ink (i.e. wetter flow or broader nibs) will better showcase its character.

• Paper choice matters: Use of good, fountain-pen?friendly paper will better preserve shading, reduce feathering, and improve the visual effects of the ink.

• Storage / handling tips: As with all inks, minimize long idle periods in one pen, flush periodically. Avoid exposure to extreme heat or light, which may accelerate fading or degrade dye stability.
