It originally is sutekinanijinoiro, which I sometimes shorten to sutekinaniji if sites find it too long, and I use that for recently created accounts for any Japanese-related site, if I choose to reveal my identity (which is quite apparent in terms of writing style and stuff, compared to accounts bearing some of my real name). For those who understand Japanese it's quite easy to get, but it means lovely colors of the rainbow, as a tribute to my indefinitely on-hiatus Blogspot, Colors of the Spectrum. ;)
