pub fn new(red: u8, green: u8, blue: u8) -> Self

Create a new LED pixel color.

pub fn from_rgb565(color: [u8; 2]) -> Self

Create a new LED pixel color from a pair of RGB565-encoded bytes.

pub fn rgb565(&self) -> [u8; 2]

Encodes the current LED pixel color into a pair of RGB565-encoded bytes.

pub fn dim(self, scale: f32) -> PixelColor

Sets the brightness of this colour.

The scale value should be between 0 and 1. Values outside this range are clamped.
