I mixed Strong Orange and Intense Blue dye stock, then dyed a standard gradation. The first one I did is shown on the bottom here:
The fabric I used wasn't my usual dyeing stuff, it was some that I found in a bin in my cellar a while back. It hardly took the dyes at all. So my next one was done with Testfabrics 400, it turned out better, but the orange is definitely washed out. Maybe my dye is just too old?
