Dark hair and color showers

[Christina Dior]

I want to color my hair im thinking burgundy or a plum like color but i want to go about it the safest way possible so my questions is has anybody with dark hair used color showers and it made a noticeable difference or did it jus look the same after you washed it out?? TIA
