* The exact shades of blonde and pink: A very light, platinum blonde will produce a different result than a darker, honey blonde. Similarly, a pastel pink will behave differently than a bright, neon pink.
* The ratio of blonde to pink: More pink will obviously result in a pinker shade, and vice versa.
* The type of pink dye: Some pink dyes are more pigmented than others and will have a stronger effect.
However, in general, mixing blonde and pink hair dye will typically result in a lighter, pastel pink or a rose gold color. If the blonde is more of a yellow blonde, the mix might lean toward a peach or coral shade.
