Programming LED fixtures with more than 3 colour sources

[niclights]

Essentially, fixtures should ideally support receiving an HSI value, and work out how best to create that colour. This would make touring and morphing a new rig a piece of cake.

 

However, this requires calibration and more processing on board compared to simply exposing each channel to DMX. Thus, it costs more - compare the price of an ETC D40 Lustr to a Qtx 6 colour PAR.

 

This is true although I've never been a fan as usually you can't get nice fades between colours in HSI. As for cost I think you would be surprised how many have HSI/V - I don't know how accurate they are but it's certainly not restricted to the top end manufacturers.
