why is my sphere reddish

Hi everyone. I am new to unity. I am doing the roll a ball. and then i saw that my sphere looks some sort of reddish. i didnt do anything to the materials… hope you can help me out… I will add a picture too.

I guess it the problem with the shader . Select the sphere go to the shader and recheck the shader and materials . Also you can check the light colour.

Create a primitive sphere and compare it
