Hi all!
Because there are various ways to set the colour of a rgb led,
i wonder does it make a difference if a colour inside a rgb led matrix
is made of multiple single colour events respectively a single rgb event?
I guess yes.
AFAIK the rgb event uses pwm to mix red green and blue.
So creating orange by simply turn on red and green is not a good way.
Is this correct?
Best regards

To be honest: I don’t understand the question.
Could you please show some .ngc code?
Best Regards, Thorsten.
Hi Thorsten,
to describe the issue without
ich bemühe mich keine Romane zu schreiben und die Beiträge auf das wesentliche meines Anliegens zu reduzieren.
Klappt leider nicht immer 
I made a ring out of 32 duo colour leds driven by three SRs connected like a 8x8 matrix.
Row 1-4 form tbe four quarters of the ring (a second ring with 32 leds is connected to row 5-8…)
Now i want to control the red color with a CC and green with another CC like this picture:
Because i did not find a better solution i simply mix green and red with this code:

Thats what i meant when I said the resulting orange color is made of two “single color” events.
Now the question:
Does it make a electrical difference to mix a led color this way instead of using the rgb=xx:xx:xx parameter?

The electrical difference between your configuration and the rgb=r:g:b is, that rgb=… allows to dimm LED brightness

Ok thank you for clarification Thorsten.
