First thing that comes to mind is Blue album and Green album for Weezer songs, just because of the titles of the albums...and Colors and Colors II by Between the Buried and Me because that's the titles of the albums. Colors and Colors II are wild emotional rides that take you all over the place and are worth checking out if you have an open mind and love for complex beautiful heavy music. I'll always associate Colors with just being the time when I discovered one of my favorite bands and favorite albums, kind of a weak experience, since the experience with the music IS the music, but I LOVE music, so finding even better music makes it an even better experience
