It sounds like we've managed to evolve this thread into 2 separate features.

First, we need a way to specify for each colour mixing fixture in a cue whether that fixture will crossfade into that cue using a CMY / RGB colour space or a HS colour space.

My only concern with this is that I believe it would only apply if crossfading from a HS value to a HS value because there are CMY combinations that cannot be represented on our current colour wheel.

Second, we should consider an enhancement or replacement to the colour wheel (like a colour sphere) that would allow us to add the concept of "intensity" to the colour model.

I don't see the calculation of the crossfade path as the problem here. We are either fading along a raw value path like CMY or RGB, or we're fading along an abstracted value path like HSI.

I do see 2 problems. First, this would mean a complete change to our colour model. I would have to verify with the development team, but I assume that a change like this would mean having to redo colour calibration on all fixtures and would most likely break the backward compatibility of show files.

Second, if we were to implement a sphere, we're talking about presenting a 3D space. We need to have an easy way to access any point in the colour space from the (2D) touch screen. One of the conveniences of the colour picker is that I can open the window and just tap on a green that I like to apply that colour.
