From my answer on the IM mailing list...
The equivelent operation in IM is -colorize which automatically preserves transparency...
A value of 100% is a total replacement of all non-transparent color components. 50% will overlay a 50% transparent color over the existing color.
See.. IM Examples, Color Modifications, Uniformly Color Tinting Images

If your original image is mostly grey, with some black and white highlights You can color the grey and keep the highlights using -tint
See IM Examples, Color Modifications, Color Tinting Greys
http://www.cit.gu.edu.au/~anthony/graph ... olor/#tint
For information on such grey highlight images.. see..
Image Transformations, Creating Overlay Highlighting

The is part however is much more 'expert' level. And is more about using -shade to generate 3-D shapes. The ideas presented are valid for all these types of images.
