I'll use my variations on the Pughe's pass as a color change over anything,
the "Onslaught Change" is an interesting application of techniques
the "Silky Change" is another one, if you can justify the position looks smooth and fluid
if you wanted a more "chest-height" change and you can get it smooth and fluid, "El Cambio Nada" is another one
my main thing about color changes, are you doing it only for a Camera, or are you actually performing in real-life, in a real-life situation, angles, clean-up, "position" and justification are the most important factors into using a color change
