dying over dyed hair

i dyed my hair with the framesi 7/56, (Medium Blonde Natural Red shade) i did not know it's permanent dye and im really scared, this was jst supposed to be like a fun thing, do u guys think itll fade in 2-3 months? or eventually?

also I want a brighter color, i was hoping to use the plum red garnier, i did my research and apparently i cant dye over dyed hair?? like i know the color wont be EXACTLY the same but if im staying in the red tones/shades wont it be approx same?

google keeps saying to bleach or use color remover and i dont wanna go thru a complex or long process
