1. 设置全局变量

COLORS = {
  RESET = { 1, 1, 1, 1 },
  WHITE = { 0.980, 0.980, 0.980, 1 }, -- #fafafa
  BLACK = { 0.294, 0.294, 0.294, 1 }, -- #4b4b4b
  BLUE = { 0.345, 0.682, 0.933, 1 }, -- #58aeee
  RED = { 0.906, 0.349, 0.322, 1 }, -- #e75952
  GREY = { 0.831, 0.831, 0.831, 1 }, -- #d4d4d4
  YELLOW = { 0.976, 0.827, 0.506, 1 }, -- #f9d381
  GREEN = { 0.553, 0.929, 0.655, 1 }, -- #8deda7
  ORANGE = { 0.918, 0.686, 0.302, 1 }, -- #eaaf4d
  LIGHT_BLUE = { 0.604, 0.820, 0.976, 1 }, -- #9ad1f9
  LIGHT_RED = { 0.976, 0.579, 0.541, 1 }, -- #f9938a
}

love.graphics.setBackgroundColor(COLORS.WHITE)
love.graphics.setColor(COLORS.BLACK)

-- change alpha channel
local color = { unpack(COLORS.RED) }
color[4] = self.scoreScreenAlpha
