I almost didn't make Supernatural icons because at first I was sad that the show was about to end and then I was disappointed by the finale (that they dropped a shippy bomb in 15x18 and then completely ignored it in the following eps is just one of several peeves). I couldn't help making Cas & Dean's icon's colors muted, not just because it fit with the show's original tone, but also due to the bleakness of their story's ending.
