Selective Colorization of Photo

I have one black-and-white image that I’d like selectively colorized. Only the main subject and one accent detail should receive color using exactly two shades that I will supply once we start.

• A layered PSD (or equivalent) with the colour layers clearly labelled
• A high-resolution flattened PNG/JPEG ready for immediate use

That’s all this job involves: apply the two colours cleanly, keep edges crisp, return the files. Let me know if you need a quick reference image for the palette.
