This color manipulation preset has a red / yellow duotone slip tint, as well as a HSL setting to let the red and green color come through.
For every color manipulation photo that I do, I always take a look at the image, think about what color will really set the tone, then play with the saturation in HSL.

You would find that these set of tinted preset all have the same base color tone for split tint, it’s a variation of the sepia effect.
