When chlorine is added to water it dissolves and forms a yellow solution. If this solution is allowed to stand in the sun the chlorine reacts with the water to form hypochlorous (HOCl) and hydrochloric (HCl) acids. Both of these acids are clear when in solution with water. In order for a color change to take place a chemical reaction has to occur and the resultant compound has to be colored. In this case, if you add KF to chlorine water, a reaction is would not take place unless there are impurities in the water, and even then it is doubtful that a product would be colored.

No change. F is the most electronegative element there is, so F- can't be oxidized to F2.
