I hope you mean chemistry unit 3 haha but for the halide tests, I normally think

chloride - white (h is the second letter for both)
bromide - cream (only two with 'm')
iodide - yellow (two 'i's look like the two 'l's)

For the flame tests, this is what helped me remember them for my exams really well

Get a white cue card and write for example, lithium = Crimson with a red flame. I then stuck this card on a red object in my room that was obvious. It seemed to work really well and as I had nothing green I just stuck that on my wall and srill remembered it. Helps soooo much!

Sounds bizarre, but I find saying the colours along to a particular TV theme tune helps me to remember.... Also for those Hallide tests you can just remember "White, creamy, yellow" in that order because when you look at the periodic table, chlorine, bromine, iodine are already in order.
