Create an eye-catching party flyer inspired by an assembly point sign with a karaoke theme. The flyer should feature a vibrant background with a mix of bright colors such as electric blue, neon green, and hot pink to suggest a lively, energetic atmosphere. Incorporate a stylized microphone as the central element to symbolize the karaoke theme. Prominently include the text "Lunes de Karaoke" in a font that complements the graffiti paint style, conveying the vibe of a night filled with music and open singing for participants. Ensure the design reflects an inviting and exhilarating environment where everyone is encouraged to join in and enjoy the music. Use graffiti paint style. --ar 3:5 --style raw  --s 200
