However, you can also use int hex syntax to set values similar to colors on the web. For example, ``0x100000`` (``#100000`` on the web) is equivalent to ``(0x10, 0, 0)``. +If you send a tuple with 4 values, you can control the brightness value, which appears in DotStar but not NeoPixels. +It should be a float. For example, (0xFF,0,0, 1.0) is the brightest red possible, (1,0,0,0.01) is the dimmest red possible. + .. note:: The int hex API represents the brightness of the white pixel when present by setting the RGB channels to identical values. For example, full - white is 0xffffff but is actually (0, 0, 0, 0xff) in the tuple syntax. Setting - a pixel value with an int will use the white pixel if the RGB channels are - identical. For full, independent, control of each color component use the - tuple syntax. + white is 0xffffff but is actually (0xff, 0xff, 0xff) in the tuple syntax. Dependencies =============
