Plotting with a custom color-vector


I've created a map with matplotlib-Basemap and will have an animated gif by
drawing my special points / markers one by one in the plot. That work's
Now the markers should have a special color from a generated color-vector.
In this vector are values from (0.0-1.0) for grey values.
The data-vector is as follows: index 0,1 the lat and lon information, index
2 the gray values.
/Problem/: Passing the color vector to the plot command, cause this error:
"*raise ValueError('third arg must be a format string')*"

This is the important part of my code:

Any ideas? Regards John
