Color
An RGBA representation of a color. Color components have an effective range of [0.0, 1.0]
, but values greater than 1 may be used.

Examples
Example using:
Lerp
RED
GREEN
YELLOW
This utility function calculates a color useful for a health bar.
function GetHitPointsColor(currentHitPoints, maxHitPoints)
-- 3 point gradient color, from red to yellow then green
local percent = 1
if maxHitPoints > 0 then
percent = currentHitPoints / maxHitPoints
percent = CoreMath.Clamp(percent, 0, 1)
end
local c
if percent < 0.5 then
c = Color.Lerp(Color.RED, Color.YELLOW, percent * 2)
else
c = Color.Lerp(Color.YELLOW, Color.GREEN, percent * 2 - 1)
end
return c
end

Example using:
Random
ToStandardHex
ToLinearHex
r
g
b
a
In this example, 10 random colors are generated. Their values are printed out to the event log in three forms: standard hexadecimal, linear hexadecimal and RGBA float values.
function MakeRandomColor()
local c = Color.Random()
local sHex = c:ToStandardHex()
local lHex = c:ToLinearHex()
print("Random color. SHex = "..sHex..". LHex = "..lHex..". RBGA = ("
..c.r..","..c.g..","..c.b..","..c.a..")")
end
for i = 1,10 do
MakeRandomColor()
end
Example using:
WHITE
GRAY
BLACK
TRANSPARENT
RED
GREEN
BLUE
CYAN
MAGENTA
YELLOW
ORANGE
PURPLE
BROWN
PINK
TAN
RUBY
EMERALD
SAPPHIRE
SILVER
SMOKE
In this example, the debug DrawLine()
is used to draw all available color constants. Trigonometry is used for calculating a circle around the player and displaying all colors in a rotating shape.
local COLOR_CONSTANTS = {
Color.WHITE,
Color.GRAY,
Color.BLACK,
Color.TRANSPARENT,
Color.RED,
Color.GREEN,
Color.BLUE,
Color.CYAN,
Color.MAGENTA,
Color.YELLOW,
Color.ORANGE,
Color.PURPLE,
Color.BROWN,
Color.PINK,
Color.TAN,
Color.RUBY,
Color.EMERALD,
Color.SAPPHIRE,
Color.SILVER,
Color.SMOKE,
}
function Tick()
local playerPos = Game.GetLocalPlayer():GetWorldPosition()
local radius = 500
local angle = math.rad(360) / #COLOR_CONSTANTS
local params = { thickness = 10 }
for i,c in ipairs(COLOR_CONSTANTS) do
params.color = c
local v = Vector3.ZERO
local theta = angle * (i - 1) + time()
v.x = math.cos(theta) * radius
v.y = math.sin(theta) * radius
CoreDebug.DrawLine(playerPos, playerPos + v, params)
end
end

Example using:
New
This example shows how to construct a new color object. The three parameters given to New()
are the three primary colors of light: Red, Green, and Blue. Here, we create a magenta color by using the values Red = 1, Green = 0 and Blue = 0.5.
local color = Color.New(1, 0, 0.5)
UI.PrintToScreen("MAGENTA", color)

Example using:
GetDesaturated
In this example, the color of a UI text is slowly desaturated until it reaches grayscale.
local UI_TEXT = script:GetCustomProperty("UITextBox"):WaitForObject()
local START_COLOR = UI_TEXT:GetColor()
local SPEED = 0.2
local elapsedTime = 1
function Tick(deltaTime)
elapsedTime = CoreMath.Clamp(elapsedTime - deltaTime * SPEED)
local color = START_COLOR:GetDesaturated(elapsedTime)
UI_TEXT:SetColor(color)
end
