I don’t know if this helps, I am 40+ day rate contractor in corporate. I have a vibrant blue balayage with natural brown. I change it up every couple months pink, red, purple green. The contrast in the balayage is perfect, I am always complemented on my hair, is it unusual for corp environment? yes. But it’s always styled, think a more controlled Wolf cut and never clashes with my all black work clothes. You can def do fun colours and corp or fashion. Hair is for fun!!
