Where does brown hair color ends and blond begins?
I have the oddest hair color that can look like both depending on light.
At night and many closed up places, it's dark and undistinguishable from brown. But in presence of clear light, like in elevators, bathrooms and in the sun, it looks blond.
Here's an approximation, but not quite it. People don't agree at what to call it, and I'm sure there are others here with the same odd coloring. It's like having glitched brown hair that lacks some "redness" to it and shines blond.
