Hi Doreen I no longer have the Emails relating to the Colorino. Effectively, however, it is a small hand-held device that identifies colours, and also contains a light probe. Of the detectors I have used, I really like the Colorino. If my memory serves me correctly, it costs round about £80, and can be bought from Computer Room Services as Steve Nutt is a Caretec dealer. Some have also bought it from http://www.ic-online.co.uk/ I hope this info is of help. Jackie Email: cairnsplace@xxxxxxx Skype Name: Cairnsplace
