No. It will totally cancel each other out and look like a weird pirplish brown. If it is really dark blue it could kind of show, but it would probably be nearly black looking. Most hair colour relates to the color wheel.
Does blue hair dye cancel out red?
The reason this happens is because blue is an ash/cool tone, and pink and red are warmer. So they tend to cancel out with each other as it returns the warm lights to your hair canceling the cooler tones. I dye my hair a lot and have had all of these happen hope that helps ya hun.
How can I change my red hair to blue?
So its possible to go from red to blue it just takes a bit, and it would be more on the darker side, but still gorgeous. As long as you are going the same level or darker than your natural level you will not need to lighten.
