However, there are subtle differences: Blue works to neutralize red and orange, while “purple shampoo is better suited to neutralize yellow tones,” says Carfi. To make sense of this, think of opposing hues on the color wheel.
Blue shampoo is not going to strip out the orange. It's going to coat the hair, giving you a tone that's both darker and cooler. Unless you bleach again, blue will give you a medium to dark ashy blonde.
Blue is the opposite of orange on the color wheel, meaning they neutralize each other; applying blue dye directly over orange hair will most likely result in a muddy brown color. To achieve a true blue color on orange hair, you would need to pre-lighten your hair to a very pale yellow shade before applying blue dye.

Blue Toner: Look for a blue toner or a blue shampoo/conditioner that can help tone down the orange. Brands like Wella, Pravana, and Matrix offer blue toners specifically designed for this purpose. Blue-Violet Toner: If your hair has a more brassy, golden tone, a blue-violet toner can also be effective.
Over time dyed hair of these colours will naturally pick up orangey tones from pollution, heat damage and even too much sun, so this is where purple shampoo comes in to help.

To avoid it going ginger or red then you must check what shade you are using. For example if the colour says golden, chocolate, mahogany, red, warm brown etc, these will all look 'ginger'. To achieve a rich colour, a basic shade must be added to create the depth (how dark it is).
