For single colours right click on the colour picker (starts deep pink) and use your mouse roller to see all the colours (Note only IE browsers can do this).
The Metallic's are from the Lotus car range, difficult to see on a web site so get yourself a Lotus brochure. Its fun too.
The ChromaFlairs are just incredible. Used mostly in the UK on TVR's these pigments are made by mixing two highly reflective metallic pigments resulting in dramatic colour changes as you walk by or the light changes. Again, get yourself over to a TVR garage to see this in action.
SpectraFlair is like a million tiny mirrors all reflecting slightly different colours and is also big on wow factor.
Finally If you want to see the flair colours before you commit (until you do its impossible to understand just how attention grabbing these are) either pop in and say hello or go to your nearest TVR garage where you'll find some of the top end TVR's in these amazing iridescent colours.
