-    Convert given RGB color decimals or floats to Hex string.
-
-    Parameters
-    ---
-    r, g, b: float | int
-        Corresponding channel value. Support decimal or float.
-
-    a: float | None, Default: None
-        Alpha value for generate simulated transparent color.
-        If specified, the returned hex color should looks like
-        rendered as `a` alpha value, on the given background `bg`.
-        Default to None, which means disable simuating transparent.
-
-    bg: int, Default: 255
-        If `a` is specified, `bg` will be used as the background
-        for render transparent color.
-        Default to 255, which means 'white' background.
