Render texture colour not correct

Hello,

I have a render texture in my 2d project, that I have created a material from and have applied it to a few different objects. However, the colour is the game view is not correct. it should be black and white, but the white is showing as blue (from the picture you can see, it shows correctly in the scene view, but in the game view it is wrong). Like I have said I attached the material to a few different objects to see if it is any different on them, but its always blue for some reason, and I cant figure out why. Does anyone possibly have any ideas. There is no skybox, it has been set to solid colour and that is what the greenish colour is. So I dont think its taking any colour from there. And from the material picture, you can see the correct colours on the sphere

If anyone has any ideas, it would be appreciated. It has been driving me insane for a few hours now
