Worked on the tabard tonight. Went with Musketeer blue. This has shading and highlights. I'm going to come back and freehand a fleur de lis on there....I'll try, anyway. I need to get an image to work from and practice it for a while.
The colors are RMS Templar Blue, the Templar Blue mixed with Nightshade Purple, and RMS Ashen Blue mixed with a little Leather White. These seem to be very nicely behaved blues - I didn't have any trouble with the highlight color going chalky at all.
