I Sing of Rage

[IceFang100]

What did you do, little clown?
[...] The walls are bleeding brown
Soon the blue to follow, then the green
Last will be the brightest red you've seen
Brightest red you've ever seen

...

Did you forget I was here?
Everything you never thought to fear
Did you mistake me for tame?
Brother, things will never be the same
Things will never be the same.

On the pet's front leg, you can see the color sequence - "brown", blue, green, "red" (with brown being substituted for grey, and pink for red, because there's no brown paint items, and no red ones that match the set).

Another Homestuck I see

One that also listens to PhemieC

Hah, yeah - fun fact: I heard this song before I read Homestuck, then again after, only realizing then that it was a Gamzee fan song. Loved it the whole time (still do, clearly)!

It's a great song!

My friend told me about this song before I started reading home stuck, too, but wouldn't let me listen to it because spoilers
