If it is a dark navy blue then under electric light it might look blacker than black - which can take on a green sheen.

The problem with black is that it takes a lot of dye to achieve black rather than grey, and an already made up garment might have linings and facings which also take up the dye, so increasing the amount required even further.

Some dyes require heat to set them, which could easily ruin your jacket by causing either the wool or other component to shrink.

I'd advise, if you can live with navy blue, then buy the jacket, otherwise, leave it be, so you are not tempted to tinker with the colour and possibly ruin it.
