RGB byte order in HyperHDR when using the SK6812 RGBW 12-volt version.

[satgit62]

Hello,
A user has reported that colours are displayed incorrectly when the 'RGB byte order' is set to 'RGB' in HyperHDR under 'Adalight LED Controller'.
However, when 'GRB' is selected, the colours are displayed correctly. See: https://discord.com/channels/407937994037919756/931706504627773450/1441844874377822252.

The user is using HyperSerialPico on an ItsyBitsy RP2040 with SK6812 RGBW CW LEDs (12-volt version).
I am aware that Neopixels use GRB internally, but I have always set RGB in HyperHDR and the colours were displayed correctly.

Could the 12-volt version of the SK6812 RGBW use a different IC with a different 'RGB byte order', meaning it is necessary to switch to GRB?
I would be very interested to know.

Hi,
I'm afraid that's irrelevant at this stage: even if it is, users have adjusted their RGB color order configurations during setup. Any change to the current color order configuration will ruin what they have, and then I'll have to read their (quite justified) complaints ;-) As for the crux of the problem, it's just as you suspect: there are no rules regarding the RGB order, and even in the case of the WS2812B, as far as I know, it is not always arranged in a GRB layout.

Thanks for the explanation!
