poisonous color

The question is: I’m making a desert survival style game. I applied a texture, but this color just eats my eyes, I can’t work with terrain, because all the slides merge with each other. How can I soften the color and add more shadows? Thank you in advance!

I forgot to add that I tried to reduce the brightness in the sun, change the color and turn off the lights on the stage, but nothing helped.

Lower the intensity on the light and you could change the shadows in the objects mesh renderer to hard shadows to make them darker. You also need objects to make shadows. I would also use a seamless texture as the texture to make it easier with a light yellow but not bright color.
