Hi
I've been using xmondo colors (and other products) for quite a while... I especially like using the colors as an underneath layer from the crown back - I've tried super purple then amethyst and just now trying the blue-purple shade shift on my natural silver/grey hair and found that the slate gray just didn't brighten my natural color - in fact it damped down my silver strands (looked a bit dreary actually). I'm hoping for a sterling silver from xmondo to help really POP my grey/silver natural hair (I've been using another brand of color conditioner because it is more vibrant and enhances my silver strands) but I really like the long-lasting relatively fade resistance of the xmondo colors ...
Pictures for clarification:
