Is it possible to change the colour direction for Hue/Saturation colour transitions?

Hi All,

I'm using S4 series 2 LEDS in HSIC mode currently.
I'm finding when I do colour transitions on the Cobalt, i.e. change from Red to Blue, that the Hue value always scrolls through the long way, clockwise.
This gives some less than desirable colour results, as we go through yellow & green.

It's be great if there was a setting to change the rotation direction so that it could go anti clockwise, which would give a shorter and more acceptable colour change from red to blue.
I've been told that on the Eos/Ion that there is a way to make this happen. Is there such a setting on Cobalt?

I accept that HSIC mode for the S4 LEDS may not be the best suited to some situations, but it's what we need to use for now.
Other fixtures using HSI modes will also have this issue.

  • Hi Ric -

    Yes, this is a limitation of Hue/Sat fades and yes, new color controls is the main new feature in the Eos family v2.3 software, coming out this summer. The plan is to take the new color controls from Eos into the Cobalt family after the Cobalt v7.3 release, which will take a little time. (There are some parts of the system we need to work on to prepare for the color controls package, among other improvements we want to make.) In the mean time, if you plan to stick with HSIC mode, you will need to plot a waypoint on your color change using an intermediate step to avoid the green range when going from warm to cool colors.

    Thanks much -

    Thanks for the quick response Sarah!
    When you say a waypoint, I assume you mean an intermediate sequence step with a different colour preset.
    What should I set for a red to blue transition to avoid the yellow & green?
    Is it based on the 0 to 360 degrees/clockwise, or is there a point or value that will take the shorter path?
    Or is it just not possible in this mode, yet?

    Hi Ric -

    Yes, that's what I mean. The thing with Hue is that it's a continuum. So, to avoid the green you might need to go white in between (take the saturation down to pull in from the undesirable/disturbing colors). I had this exact problem when I used this mode for a trade show. In the end I adjusted my design so that the transitions weren't so glaringly green by changing my middle color, but going from a deep red to a deep blue via Hue by nature has to pass through green - it's like crossing a rainbow, you can't jump from one edge to the other without falling off, you have to skate through the yellow/green middle.

    I'll have a chat with the team, though, to see if there's anything small we could do in the mean time to make this better - but I'm not sure if there is. I will let you know.

    Thanks -

    Hi Sarah,
    OK, a possible fix for us is to go to RGB mode.
    Does RGB mode have a better colour transition?

    If we reset all the fixtures to RGB, and recreate the colour palettes to match the colour palettes in the current file AND the fixtures use the same channel numbers, will my presets look the same?
    I.e the goal is to avoid having to go through each preset and recreate colour information.

    I'm hoping the the channel & palette reference will swap across...

    Hi Ric - I recommend taking one fixture in the new mode and with a new address, patched to a new channel number, and using that create the new by type colors that match the others. Then give that fixture its old address back and change the mode on the existing channel patch. Make sense? That way the old patch isn't really disturbed. (And always work on a copy of the show, just in case.)

    Thanks Sarah,
    I'll give this a try when I'm back in front of the desk tomorrow.
    Fingers crossed !

    Hi Sarah,

    Unfortunately the above didn't work. The palette references seemed to be there, and intensity was showing, but the actual colour wasn't changing.
    Strangely enough looking at the fixtures selected showed the colour palette name changing on the fan attribute (showing on the device dock), but RGB values stayed at their last fixed setting.

    We've gone through and updated the show file based on the colour palettes used, referencing the name shown on the fan attribute, and the transitions are definitely better in RGB.

    Thanks for the assistance.
