Hey Jules,

I would imagine that the burgundy colours would be cyanotic - they show a problem in circulation in that limb anyway - and the grey shading would also suggest a compromised circulation. I could be wrong but I think the less an individual is able to move the affected part the more pronounced the colour changes are eg - for me, my legs are black, BUT that's because I can't move them, whereas others who can, would still suffer with the cyanosis, but because they have the ability to pump the blood through muscle movement it would be less pronounced.

Well, that's my 2cents! - Vicc, come and correct me!!!
Love
