Aurora Orange is a solid orange, leaning slightly red in saturated areas. There is some lovely (subjective) silvery sheen at the edges where the ink pools, but none that I’ve seen during normal writing in wet broad nibs. Even if the ink seems to want to shade, it doesn’t quite there in my nib and paper combos. It’s bright and cheerful, and a bit redder than Sailor Apricot and Kin-Mokusei. It is similar to Scribo Arancio di Sicilia, which is slightly not as clean and clear; it’s also similar to Jacques Herbin Orange Soleil, which has less sheen. The ink flow is average and it feels ok under the nib, as far as orange coloured inks can be labelled as being smooth. I will use it for proofreading and marginalia, as it nicely contrasts with black text. It’s not an eye-searing colour, but full pages of handwritten notes might be tiresome for some people during readback. All in all, a very nice ink.
