Favourite colour?

Green! Oh ahr no blue! (falls into chasm of doom)

The colour question is easily correctly remembered (and hard to guess) if you actually have a favourite colour. For example, #993333 (in HTML) or {.39 .13 .13} (in PSTricks/LaTeX) or whatever. Just use your favourite coordinate system, being RGB, CMYK, HSV, or other, with numbers 0.0--1.0, 0--256, 00--FF, or other. The problem is to invent a favourite colour and stick by it --- probably easiest is the colour code of your car's paint, as needed for small repair jobs.
