In Imaq there is a Vi called rgbtocolor2.vi that is useful to convert an RGB into Cie lab color code. Is there another vi in order to convert a color in the CIE lab color space into RGB ?
I'm pretty sure there isn't a VI to do the reverse conversion, so you'll need to code it yourself. The NI implementation of La*b* seems to be a little non-standard - see http://forums.ni.com/t5/LabVIEW/La-b-colour-conversion/td-p/1646458 - I think the issue is that LabVIEW doesn't do a gamma correction, whereas most other software does.
