Congratulations!!! You are Slate! Part of the Metamorphic fam.

You like to break it down while remaining on the calm side, and keep things pretty serious. Note how the slate has ridges and grooves, yet they are not too crazy, this is directly interpreted to having an urge to dance and have fun, while still being a bit stern, and maintaining the calmness. The gray color translates as a quite serious color which is what you are. You like to have fun while still taking life seriously... just like your new bff Slate < 3
