颜色的成功转换,这个就是颜色的一些操作。
magenta=color 255 255 0 255 -- create colors using constructors
aqua = [0, 6, 2] as color
aqua.v /= 2. -- reduce "strength" of aqua color
---这里是求出,.v 的最大的值,这个很重要。
aqua
aqua.alpha=128 -- set aqua to 50% opacity
aqua
lightGray=white/4 -- create light gray color by dividing
-- each component of white by 4
composite aqua lightGray -- composite light gray over aqua
random black white
