How to change the old black-and-white photos of military uniforms into new color photos of military uniforms?

PS is not everything. If you want to change the old black-and-white photos of military uniforms into new color photos, or you need software that can change the black-and-white photos into color photos and change the old military uniforms into new military uniforms, or you can use methods such as coloring and dressing up in retouching software such as PS to restore the old black-and-white photos of military uniforms into new military uniforms. The effect depends on the level of retouching. I only know that ordinary level retouching will not work well, so it is better to shoot directly, saving money and effort.

I hope to adopt.
