It is not exactly what you want, but you could take a look at the HeatmapApi.

There is a free version for max. 100 datapoints. The main limitation regarding your requirements is that you cannot adapt the color scheme. This feature is announced on their web page but without a date.

I tried the API in the last few days and it works as expected and promised. It is provided as web service and takes parameters in the format [lat, lng, value] to compute the heatmap.
