What is the color of bromine liquid?

Explanation:
Bromine liquid has a deep reddish-brown color. This comes from how Br2 molecules absorb light: they absorb much of the blue‑green part of the spectrum, so the light that reaches our eyes is mainly red‑brown. The liquid’s appearance isn’t orange, green, or pale yellow because those colors would correspond to absorbing different parts of the spectrum than bromine does. In everyday lab observations, bromine’s liquid consistently looks red‑brown, not the other options.
