Color Behavior & Optical Properties

• Dategokoro is engineered as a color?shifting ink: the hue evolves as it dries, influenced by paper type and saturation.

• Its color transition tends to move from greenish or teal initial tones into deeper purples, indigo, or blurple shades as it settles.

• Shading is pronounced: lighter strokes show softer tones, heavier or more saturated strokes deepen the color.

• While it has no shimmer, the ink is noted to produce sheen / halo effects under favorable conditions (i.e. where ink pools or in concentrated strokes).

• Water resistance: none — the ink is not water-resistant and will fade or wash if exposed to moisture.

• Drying behavior: not fast-drying; heavier application or wet areas may require longer drying times, especially on less absorbent paper.

Performance & Usage Notes

• Flow & feel: Generally smooth and well-behaved for fountain pens

• Start / reliability: No prevalent reports of skipping or hard starts with typical use

• Feathering / bleed / show?through: On good, fountain-pen-friendly paper, performance is solid; on more absorbent or lesser-quality paper, nuance may be lost or show-through may increase

• Cleaning & maintenance: Because it is dye-based and free of particles, it should flush cleanly from pens and feeds without excessive residue

• Community observations:
   - Users describe Dategokoro as a “dark blurple” with red sheen — the sheen gives a purplish look as it dries
   - The shifting effect is highly dependent on the paper used; in some cases it appears more indigo / bluish, while in others more reddish / purple
   - Some note that lighter or thin strokes can cause the color to appear muted or greyish before the shift fully develops
   - One reviewer mentions that while it writes beautifully, the actual color tends toward deep blue-purple rather than the brighter depiction seen in images
