Problem while importing texture

Hello everyone, I imported this texture on Unity, everything is fine the texture is the same as the original, but when applying it it seems like the beige is wayy more visible (the bott left is the original image, on the terrain is the texture that is wrong).

It isn’t a lightning issue as even putting the dirrectional light intensity to 0 doesn’t change anything, and not the terrain issue because it doesn’t work on other objects (i tested with a plane).
I also tried changing the compression of the image and the filter but it doesn’t change anything…

For anyone having the same problem;
I “fixed” it by playing a bit with post processing settings, mostly: contrast, saturation, color grading.
