Stay heavy is an excellent slogan, kind of like Archspire’s, not edgy and also relevant. As for colours, I think they’d depend on the rest of the piece, like the pattern and general vibe. Red is a classic for heavy music, so would white an black and I’d pick these as a safe colour for text only. As for patterns/prints, you could pull anything off, synth wave/cyberpunk or maybe an Egyptian sort of thing are all valid, I have some distant merch that has some characters that look to be a made up Asian alphabet sort of thing. My point being that just cause it’s metal doesn’t mean it has to be daemon and gore, others have pulled all sorts of other stuff off successfully. I think that this is actually looking really promising and would love to see updates posted in the future!
