Color Behavior & Optical Qualities

• Color shift / transformation:
   Hanagokoro is a dual-shading ink. When freshly applied, it leans toward a soft pink or floral tone, and as it dries (or depending on the paper), it shifts toward a subtle gray?green or muted tone. Sources describe it moving from pink to gray-green.

• Dominant hues & transitions:
   Lighter strokes emphasize the pink / floral cast; heavier or saturated pools may reveal a greenish or gray undercast.

• Shading / nuance:
   Shading is fairly strong — light lines remain delicate in tone, while thicker lines deepen considerably.

• Sheen / halo effects:
   Although it contains no glitter, some reviews mention that in heavier saturation or pooling, a sheen or halo effect can appear (i.e. a subtle reflective edge).

• Water resistance / permanence:
   None — as a dye ink it is not water-resistant; exposure to water or moisture will degrade the appearance.

• Drying / behavior:
   Not a fast-drying ink; in heavier use or on less absorbent paper, drying times can be longer.

Performance & Practical Notes

• Flow & feel: Described as smooth and well-behaved in fountain pens

• Start / reliability: No frequent reports of skipping or hard-start issues

• Feathering / bleed / show-through: On good quality, fountain-pen-friendly paper, the ink behaves well, with minimal feathering. On lower-quality or absorbent paper, nuance and clarity may suffer, and show-through may increase

• Cleaning / maintenance: Being a dye ink without particulate additives, it generally flushes cleanly from pens and feeds

Community Impressions & Unique Observations

• One user described the ink on a forum as:

  “A dusty grey?purple base with reddish brown sheen … the sheen looks a lot like that oily ballpoint sheen.”

  This suggests that under certain conditions, the sheen is quite noticeable on top of the main hue.

• It’s often noted that the final look of Hanagokoro varies greatly depending on paper and nib, with some users experiencing more pink tones, others more muted gray-green, depending on substrate and ink load.
