| Development |
The color changes depending on the paper, and when the ink studio 224, 252, and 280 were developed, the prototype was removed because "the color changes are too severe and the color is not calm and it is difficult to commercialize it even on normal paper." There were some colors.
The project started to be reproduced by the ink blender Ishimaru at that time, and the project started for commercialization.
"Fluctuating ink" was a challenge to commercialize "fluctuating" colors.
I repeated the prototype with Ishimaru with the in -house members, but the adjustment of less than one drop of a dropper made it a completely different color, and it was not quite a color that I aimed for.
Meanwhile, it became a kolona whirlpool, and the exchange was even more difficult.
The color of the sample changed depending on the number of days since I wrote it, and the color that could be seen differs depending on the fluorescent light at home, so there were many exchanges such as "This green" and "Eh? Brown?" 。
I conveyed the color I imagined in images and words, and repeatedly had the prototype again, and finally the candidate color was aligned, especially "fluctuating".
Each color, such as the color that changes from the moment of writing, and the color that can be seen in various colors in the shade, is really fun.

By all means, I hope that you can sympathize with the fun of the flickering ink.
