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.

Class Functions

Class Function Name	Return Type	Description	Tags
`Color.Lerp(Color from, Color to, number progress)`	`Color`	Linearly interpolates between two colors in HSV space by the specified progress amount and returns the resultant Color.	None
`Color.Random()`	`Color`	Returns a new color with random RGB values and Alpha of 1.0.	None
`Color.FromStandardHex(string hexString)`	`Color`	Creates a Color from the given sRGB hexadecimal string. Supported formats include "#RGB", "#RGBA", "#RRGGBB", and "#RRGGBBAA", with or without the leading "#".	None
`Color.FromLinearHex(string hexString)`	`Color`	Creates a Color from the given linear RGB hexadecimal string. Supported formats include "#RGB", "#RGBA", "#RRGGBB", and "#RRGGBBAA", with or without the leading "#".	None

Examples

Example using:

`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

`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:

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)

`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
