I am so happy to see that I am not the only one who has problems with the difference between these colours. Teal is not so much a problem for me but I have always thought of Aqua and Turquoise as synonyms. Many things are incorrectly named as well – the Filofax Aqua Malden was more jade than aqua I think (well at least my ones are)

Anyone else have any input or opinions on the suggestions below?
