Why is my texture when I apply to my terrain so dark?

Comparing the picture in the thumbnail of my grass to the grass showing up in my terrain it seems significantly darker. This isn’t just for grass either, its for my dirt as well. I have added only o ne source of light atm. Any suggestions would be greatly appreciated. Cheers!

Try changing the shader on the material on which the texture is applied. Try ‘Unlit’ shader. Or you can use simple ‘Diffuse’ shader.

Change the shader material to Unlit > Texture

I know this might sound silly but if you are using the Standard Shader for your material you might have the albedo color set to a darker one.
