Directly after drying, when the ink is already smudge-proof, they still appear noticeably darker with me. After complete drying (tested after one day) remains the color described by me on paper.
The ink itself like it very much of their technical characteristics. Hue is among my personal constraints (writing instruments and paper, writing style) but misleading.
So four stars for excellent ink. One star less because the color name under my conditions is misleading, anyway.
