crystal.Color

A color, with RGBA components.

Color components are stored in the array part of these objects. This makes them compatible with LOVE functions that expect colors as {r, g, b} or {r, g, b, a} tables.

Constructor

crystal.Color:new(hex_rgb, alpha)

The hex_rgb parameter is a number (not a string!) listing the RGB components of the color (8 bits per channel). If nil or omitted, it defaults to 0x000000 (black).
The alpha parameter is a number between 0 and 1 indicating the color opacity. If nil or omitted, it defaults to 1 (fully opaque).

local black_opaque  = crystal.Color:new();
local pink_opaque  = crystal.Color:new(0xFFC0CB, 1);
local turquoise_transparent  = crystal.Color:new(0x30D5C8, 0.5);
