Colour Ring Numbers and letters?
(1) What does 'R' mean? ( e.g. 10R)

(2) What does a 'RD' mean ? (e.g. 6RD)

I know the last 2 digits are percentage of grey hair ...for example I assume 1710 would be colour 17 + 10 percent grey (correct?) However ....

(3) Is colour 7 related to 17 or 8 related to 18? Or are these just 4 different shades with no connection?

(4) 17 and 18 look the same to me ....what is supposed to be the difference? .... . do I need an eye test? :geek: Smile

Thanks for any replies .. might help me finalize decision.
