Hi, Some time ago, there was a thread about what color spaces to include in scikits.image: http://groups.google.com/group/scikits-image/browse_thread/thread/4b4e69fd0d... I wonder if you would be interested in seeing more color space conversions being added to the colorconv.py module, or if you are deliberately keeping it simple? For instance, I would like to add conversions to and from CIE LAB, and to allow alternative white points. I'm also interested in seeing conversions to and from human cone LMS spaces available somewhere for SciPy users. I'm not sure whether or not this kind of thing would be appropriate for scikits.image. I thought I should first post a short message about this before starting anything. I'm aware that the SciPy image sandbox used to contain more conversions, probably in a slightly confusing way (e.g.http://projects.scipy.org/scipy/browser/trunk/Lib/sandbox/image/ color.py?rev=1698). Anyway, please let me know what you think. Thanks, Chris
