projecthello.com has color-coded lyrics up (some stuff missing, like color-coding of TMS [like we need it lol] and the entire page for Aisereta no ni [edit: nevermind, fixed])

I'm just glad to see the color-coding for the Seishun domannaka even though I'm starting to learn to distinguish their voices (mostly Ayumi from Haruka).
