I have created an EWB Colour Inspector app which may be of interest.
It allows you to search for colors using ARGB (decimal), RGB (decimal) or ARGB (hexidecimal). It also displays all the named colors that Tim defined in webui unit and a number of their attributes.
You can list similar EWB named colors to the selected color as well as 5 shades of lighter and darker colors for the selected color.
Application has placed in the Demos and Examples forum.
