Color picker tool and AD generate different RGB values

[Coconut42]

Hi all,

 

just got a color picker tool called ColorTagGen from the Mac App Store and have this weird effect that even when both it and AD use the same sRGB color space then the same HSB values generate quite different RGB values, much more than could be accounted for by rounding errors or similar.

 

Now I'm no expert on color spaces, but given the same color space and the same input I would expect the same output - is this a bug in one of these applications or am I missing something important?

 

Thanks!
