Shader Turning Grey instead of White so I was following a tutorial on making detailed eyes, I don't know why but as I was making the shader, it's colouring the eye grey even though the gradient is clearly set to white?
Here's a picture of my shader,

As you can see, it's set to white, but even if I drag the gradient to fully white, it still looks a light grey...
Any help would be appreciated, thanks!

Edit: For reference, here is the tutorial I was following, https://youtu.be/E0JyyWeptSA?t=558
You can see even though it appears my settings are the exact same, his is a consistent white in the middle, whereas mine is a dark grey...
Set the Z translation to 0 instead of -0.5 in the mapping node. What you are seeing here is a cross-section along the bottom of the sphere gradient, instead of the middle cross-section.
