I thought I would document this here as I had trouble finding the information when reviving the Beeb Speak boards. They contained a capacitor with a now defunct colour coding system. Here it is:

Right hand lead is positive when viewed from the spot side		Digits	Multiplier	Working Voltage
	Black	0	x 1 µF	10
	Brown	1	x 10 µF	--
	Red	2	x 100 µF	--
	Orange	3	---	--
	Yellow	4	---	63
	Green	5	---	16
	Blue	6	---	20
	Violet	7	---	--
	Grey	8	x 0.01 µF	25
	White	9	x 0.1 µF	3
	Pink	---	---	35
