How Pa selects the front panel color for his FW products? Is the secret in these pages and I failed to find it?

Anyone knows or want to guess? Please tell me or I will lose my sleep.

And what if Pa would gift all of them (except SITs) to you but you could only choose one color? Which one would you pick?
