Using Adobe PhotoShop CS. Includes Selective Coloring, works usually with greenish/yellowish pictures. 3 Steps Only!!
01. Duplicate your base. Set it to Soft light or overlay. I used Overlay, it won't mess up your result, though.
02. Flatten your Image.
03. Layer >> New Adjustment Layer >> Selective Color:
Reds: +100 -17 +100 0
Yellows: +100 0 +100 0
Neutrals: +74 +100 +46 0
Done! Wasn't that simple? I'd love to see your results!
