SK6812 - solid color - blue

Hi,

i use the SK6812 LEDs. When i try solid color blue then the white LED shines a bit.
In comparsion with the ws2812b the SK6812 blue is light blue.
Red and green are fine with both LEDs (ws2812b and sk6812 (white is off)).

I try all white channels like none, brighter, accurate… but no changes

Is it normal or is it a bug?

That’s sadly normal. There is bleed between the dies.
