@ -1607,6 +1607,16 @@ To specify the value of the alpha channel, append `#AA` to the end of the color
(e.g. `colorname#08`). For named colors the hexadecimal string representing the alpha
value must (always) be two hexadecimal digits.
`ColorSpec`
-----------
A ColorSpec specifies a 32-bit color. It can be written in either:
table form, each element ranging from 0..255 (a, if absent, defaults to 255):
`colorspec = {a=255, r=0, g=255, b=0}`
numerical form, the raw integer value of an ARGB8 quad:
`colorspec = 0xFF00FF00`
or string form, a ColorString (defined above):
`colorspec = "green"`
