I can recommend Sean's NT version of Bmp2Ico - its terrific.
But the problem is worse than just 16x16 bits - the lowest common denominator here is 4 bit colour depth. The default windows setting for icon display is for just 16 colours; you have to go to Control Panel|Display|Effects and tick the box for "Show icons using all possible colours" to see them in glowing 8/24 bit technicolour. The chances are most users will either not know about this or will not have bothered to change it. I am aware of this because having created a very nice bitmap in 256 colours and converted it to an icon with Sean's program, I then tested the program on a friend's PC to discover that my lovingly created icon was displayed as a splodgy mess - the answer of course was that I was seeing it in 4 bit colour for the first time - moral create icons in both 256 and 16 colour versions as well as the array of various size options. Windows in 4 bit icon display mode will just choose the nearest available colour - the chances are this will not be what you intended.
Here is a palette file I use which contains just the 16 system colours. If you copy it to the Xara X palette directory it will appear in the colour gallery next time you start up Xara X.
