I was all ready to say "That would be rather involved" and then I realised that you're probably referring to the X-axis labels - not the Y axis labels. This makes it somewhat easier.
There's still nothing built-in that will do what you want, but what you can do, is use the draw event to have some custom code run to draw the labels yourself and this way you can determine the color based on the data.
