Kitchen scene shadows

setting up the grass in this kitchen scene, i have added a tree alpha infront of the sun to create dappled sunlight on the ground, however the shadows seem incredibly dark on the grass in comparison to the wood/concrete. any tips on how to combat this?

Your shadow is rather blue and there is not much blue in the grass material… mind you the same is true for the yellow/brown floor…

Maybe take a screenshot that shows as much information that might be relevant as you can.
