Your issue looks rather similar to this one: 
http://code.google.com/p/jsc3d/issues/detail?id=58.

The problem is the color you passed in to construct a new material should be a 
number rather than a string.

By the way, you might have noticed that the shading on the cube is a little 
strange. It is caused by excessive averaging when computing vertex normals from 
face normals. Jsc3d provides a solution to deal with this: tell the viewer a 
appropriate crease angle to preserve sharp edges and remove the unpleasant 
shading. It requires just an additional line in the initialization phase:

  viewer.setParameter('CreaseAngle', 30);

More details of the parameter 'CreaseAngle' can be found in this document:

Thanks a lot for the prompt reply. Really appreciate it
Have converted the color string to number and the code now works.

For newbies - to convert colour string to number
color = color.slice(1);  //where color is defined as "#FF0000"
colorNum= parseInt(color, 16);

Also, need to know how to save the same object with the new selected color.

Thanks for posting your code snippet! I'm using this to do the conversion:

  parseInt('0x' + colorString.substring(1));

It outputs the same result :-)

Saving is NOT supported, though it can be implemented with HTML5 File API. It's 
not in my plan.
