Fading colours on Eos and Source4 Lustr+

I'm running some Source4 LED Lustr+ units on an Eos ... they're in HSIC mode.

Is there a simple way to fade directly from one colour to another without going around the circumference of the colour picker wheel as the 'hue' value changes? For example, let's say I'm in a dark blue and I want to crossfade to an amber without going around through bright pink on the way - other than completely changing the mode in which I'm running the fixtures, is there some trick I can employ to achieve this?

    Gareth,

    In my experience, S4LED Lustr+'s are basically impossible to control in HSIC or +7 mode.  You'll have much better luck with Direct mode.

    The only drag about Direct mode is that the fixtures won't be calibrated, which may be a problem if you're lighting a white cyc or similar.  Generally it's not a problem if you're lighting scenery or people.

    I hear ETC is working on a better way to control Lustr+'s in the calibrated modes.

    If you open up the color wheel in the color picker, you will see how the transition progresses thru the colors.  One trick I've heard of is doing an autofollow point cue(s) that moves the color the other way around the wheel so as to not be as noticeable.  

    Let us know how this works, if at all !

    Just to add to the list of work arounds... use discreet timing on the hue and sat channels. So if its a 4 ct, set hue to a time of 3 and the the sat to a time of 1 with a delay of 3 (or whatever magic combination you find). In  theory the light will work its way around the color wheel to get to the right color and will then change it saturation to get lighter / darker within the color you want. Still not the best solution, but at least it won't pass thought white on its way. While not exactly the same, I used to do this with CXI's all the time  to avoid both strings passing through white at the same / nearly the same time.  Its a similar concept to Ueliriegg's suggestion, but without adding an extra cue. Ultimately I agree with the suggestion of running the fixture in Direct mode if you have the DMX space to do so. You can still use Hue Sat controls if you like to color mix that way, but fades can occur in a native color space and you have greater control if you really need to nit pick on colors.
