Step 1: Prepare your base. Crop, screen, sharpen, etc. I only cropped this picture.
Step 2: Open a new selective colouring layer (Layer >> New Adjustment Later >> Selective Colouring) and input these numbers:
REDS: -100, 0 , +35, 0
YELLOWS: -100, 0, +100, 0
WHITES: +100, 0, 0, 0
NEUTRALS: +20, -10, -20, -20
Step 3: Open again a new selective colouring layer.
REDS: -100, 0, +100, 0
YELLOWS: -100, 0, -100, 0
