Answer
The easiest way to create an effect like that with precise control is using a Gradient Map.
Start with a normal colour image.
If you apply a Gradient Map Adjustment Layer on top, with a pink to black gradient, the effect will be identical to what you’re after. It even means you can choose precise colours for anywhere along the tonal range. I’m a big fan of Gradient Maps.
