Color matching between Colorsource and lustr

[jgels]

Hi all,
So we have a bunch of colorsources that we have programmed colors for our show on. We don't have any but are going to a festival where we need to match our colorsources colors with a lustr. If we just put the same values into red green and blue, will we get the same colors?
Thanks

No - the emitters are different, and the arrays of emitters are different on top of that.

I generally find the best result is to utilize the built-in gel libraries, but limit the choices to ones that both render equally well. Tgat generally means staying within the Colorsource's gamut

If both fixtures are in RGB mode, they should match reasonably well. (RGB on these is a calibrated mode, rather than direct control of the individual emitters)

If not, when you switch the profile in the show file(assuming you are using an ETC console), the console will try to match the colors as best it can.

Since these are both ETC fixtures, if you use HSI values(either in HSI mode on the fixtures, or with virtual HSI enabled on the console), the colors should match pretty well.

See, that was what I thought too: the RGB was a "hint" to the fixture, which is recasting it into 4 or 6 color elements (depending on which fixture it was).

It is how it's supposed to work, but the lustr is likely to be closer to standard colours and open whites than the colorsource as it has more emitters. But they will be close - we did just that when we did a fixture shootout and the difference was noticeable if you looked for it, but not horribly glaringly wrong.

note that this only works on fixtures that take the RGB value and do the math for extra emitters. Lights that only have RGB emitters, or some other types of lights that simply turn off extra emitters when in RGB mode, will not match.

Indeed so, which is what the colorsource and lustr fixtures do when in RGB mode. You're not going to get anywhere near as good match with other fixtures - we saw that strikingly when we compared fixtures and when asked for a 3200K white the colorsource was good, the lustr (of course) better but the Martin fixture had a definite colour cast that you'd have had to tune out to match.

This thread is a good example of why you should not mix fixture types in a single system. IE don’t put a color source and a luster as front light.
