版本：Matrix OS 4.0 🚧

Color API

Overview​

Most LED and UI APIs accept RGB tuples directly, such as (255, 0, 0). Use MatrixOS.Color(...) when you want a packed RGB value that can be stored, reused, or passed through code as one integer.

The return value is a packed RGB integer in 0xRRGGBB form. RGBW input is accepted, but the returned integer stores RGB only; the white channel is not preserved in the return value.

import MatrixOS

red = MatrixOS.Color(255, 0, 0)
green = MatrixOS.Color((0, 255, 0))
white = MatrixOS.Color(255, 255, 255, 0)

MatrixOS.Color​

MatrixOS.Color(value: int | tuple[int, int, int] | tuple[int, int, int, int]) -> int
MatrixOS.Color(r: int, g: int, b: int, w: int = 0) -> int

Creates a packed RGB color value.

Parameters:

  • value: Existing packed RGB integer, RGB tuple, or RGBW tuple.
  • r: Red channel, 0..255.
  • g: Green channel, 0..255.
  • b: Blue channel, 0..255.
  • w: Optional white channel accepted for RGBW input. The packed return value keeps RGB only.

Returns:

  • int: Packed RGB value in 0xRRGGBB form.

Use RGB tuples for simple one-off LED calls. Use MatrixOS.Color(...) when you want to keep a color in a variable, save it in settings, or share the same value between LED, UI, and color-effect code.

Store A Color​

import MatrixOS

# Store a reusable accent color as one packed integer.
KEY_ACCENT = "HelloPython accent"

# If the app has never saved the key, default to cyan.
accent = MatrixOS.NVS.get(KEY_ACCENT, MatrixOS.Color(0, 255, 255))

# LED APIs accept the packed color directly.
MatrixOS.LED.set_xy(0, 0, accent)
MatrixOS.LED.update()
