Someone tell me what colour Mercury (Hg) produces in a flame test.

You observe it through a spectroscope and you'll see many lines of many different wavelengths

9.9.6, col 3, dp 1 :

identify data, choose equipment, plan, and perform a first-hand investigation using flame tests and/or spectroscope analysis as appropriate to identify and gather first-hand information to describe the emission spectrum of a range of elements including Na and Hg

Apparently we use a gas discharge tube :/

I'm guessing the discharge tube would excite the electrons so then you can observe the emission spectra

Yeah but the only picture I saw of it was dodge. It looks kinda Aqua-Bluey-Whitey-Purpley or something.
