Can anyone explain why this color is purple?

So I’m fairly new with Shaders and Shader Graph, right now I’m doing a combination of tutorials and experimenting.

I’ working on trying to lerp colors and textures and I keep coming across this result:

So here I’m trying to lerp between grey and green based on an object’s normal vector. Why is it turning purple though? I cannot figure this out.

When I switch out the colors for textures I have the same thing happening. I’d really appreciate some help with this!

Lerp is not clamping values, so it overshoots. You need to clamp it between 0 and 1 if you want to get expected result.
Or remap [-1, 1] to [0, 1] as this is what you are going to get from normal vector.
BTW, inverse lerp might work not how you expect.

Not sure what you mean about the inverse lerp not working how I expect, but the clamping did the trick! Thanks so much!
