OK, looks like it's a chco issue not a chd=t: issue. You should use pipe characters to separate the colors for data point 1 in data sets 1&2 then use a comma to separate the colors for data point 2 from those of data point one. Like this:
http://chart.apis.google.com/chart?cht=pc&chs=450x450&chd=t:10,20,30,40|10,20,30,40&chco=FFFFFF|009900|000099|000000,FFFFFF|009900|000099|000000 Check out http://code.google.com/apis/chart/colors.html#chart_colors for some other examples. Basically the pipes are the data point separators and the commas are the data set separators here. Hope it helps.
