    I know that Bromine in it's natural state is a dark red/brown liquid, and I know that when KBR is reacted with Cl it produces a yellow solution.

    I this question:

    "The extraction of Bromine involves displacing the Bromide ions in HBr using Chlorine, to produce Bromine. Describe what you would see"

    I wrote a yellow solution forms, but the answers said that a dark red/ brown solution forms. So is it only yellow when the Halide ion is bonded with potassium (i.e KBr) reacting with a halogen (Cl)?

    You're both correct.

    It's a concentration issue.

    Well if Cl displaces Br to form KCl( remember all group 1 salts are soluble so no precipitate and form colourless solutions) then the Br2 liquid is formed and bromine liquid is orange brown in colour then all you would observe is colour differences when bromine is displaced.
