Fader for cycling through colors


Recommended Posts

Dear Team,

need a good idea/solution: Let's assume some RGB-fixtures (some washer for background lighting). For a live-show I want to change the colors just by moving one fader up/down, cycling through some rainbow-colors. Similar to the rainbow-effect, but not on a timely base, but on a fader-position-base. No need to change brightness, just assume 100%.
Maybe there is a solution with fader-position down (0) for black, and values 1 to 255 for different colors (in full brightness).

Ideas? Sounds tricky, does it?

Thanks,
Kay

Some LED fixtures have a colour macro parameter that allows you to do exactly this, I'm guessing your fixtures don' have this?

Could you simply select these fixtures, and then use the colour picker live?

Thanks, Edward, you are right: RGB is the only we can use, as "smallest common property".
In fact I am more the "a fader is a fader is a fader"-guy, instead of touching and whiping.

The "color picker solution" will look like this:
1) Select Group-Window
2) Select group(s)
3) Change to color picker
4) Search for the small cross showing the current color
5) Try to hit the cross as near as possible, otherwise colors on stage will jump
6) Slowly move finger to the new color
7) Eventually start again at step 1) for next groups

The "Rainbow fader solution" will work like this:
1) Move the fader(s) to the new position

Maybe I will do the "3-fader RGB-trick", so I could control 8 groups on one page (on FLX S24), which should be quite enough.

But I will still be open to a "one fader rainbow cycling"-solution ;-)

Thanks,

Kay

Hi Kay,

What you are after is a "hue" channel, allowing you to cycle through the hues you want using a single parameter. Unfortunately unless there is a macro/hue channel on the fixture, there wouldn't be a way of creating a hue parameter for you to then record on the console.

What you could do is record a rainbow effect for your fixtures on one playback, and then set up a speed override on another playback. You could then run the rainbow effect, and the various colours would start to cycle, and you can then bring your speed override fader down to stop the effect when you get to the colour you're after. Remember speed override will affect the currently viewed playback.

You could then record a separate intensity fader, and enable fader controls colour on the rainbow playback, giving you intensity on one fader, saturation from the rainbow effect playback, and then use the speed override fader to choose the hue.

If you have any questions let me know.

Short answer is NO 🙂
This thread gave some really helpful images (I like "RGB Blur", because "original" color picker image is mostly white at the bottom, so space is wasted which could be used for more colors/shading). I also use the image you posted above.
But, as you said, original issue (rainbow-fader) is still open.
Greetings,

Okay, so in summary I will use 2 methods:

1) Selecting groups "live" and just use jog-dials to change R-G-B-values, or
2) Use the RGB-3-Fader-trick for every group of fixtures. 8 groups will fit on one page, so still 24 faders left on second page.

Thanks for ideas,
Kay
