I was looking on TMP :-[ and found this useful chart
http://scalemodeldb.com/paint
good find :-bd
That IS clever.....Though I assume different folks' screens won't necessarily show identical colours ? :-\
But a very good starting point.

I've used that site in the past, I wasn't too impressed with some of its 'matching' colours.
I suggest you try some colours you have similar shades for from different ranges and see if it recognises them as matches.

Thanks! Useful. Ditto what Techno said.
