@ -21,12 +21,12 @@ Colors are stored as tuples by default. 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.
