Arguments
number red
- The amount of red.
number green
- The amount of green.
number blue
- The amount of blue.
number alpha (1)
- The amount of alpha. The alpha value will be applied to all subsequent draw operations, even the drawing of an image.
Returns

Function
Available since LÖVE 0.7.0 |
This variant is not supported in earlier versions. |
Synopsis
love.graphics.setColor( rgba )
Arguments
table rgba
- A numerical indexed table with the red, green, blue and alpha values as numbers. The alpha is optional and defaults to 1 if it is left out.
Returns
Nothing.
Examples
Set the color from r, g, b bytes
Using love.math.colorFromBytes we can specify color components in the range 0..255.
love.graphics.setColor(love.math.colorFromBytes(128, 234, 255))
Draw a red, blue and green circle
function love.draw()
love.graphics.setColor(1, 0, 0)
love.graphics.circle("fill", 50, 50, 20)
love.graphics.setColor(0, 0, 1)
love.graphics.circle("fill", 50, 100, 20)
myColor = {0, 1, 0, 1}
love.graphics.setColor(myColor)
love.graphics.circle("fill", 50, 150, 20)
end
Display a Venn diagram
function love.load()
baseX = 300
baseY = 400
radius = 100
offsetY = radius*.5*math.sqrt(3)
love.graphics.setBackgroundColor(1, 1, 1)
end
function love.draw()
love.graphics.setColor(1, 0, 0, 0.4)
love.graphics.circle('fill', baseX, baseY, radius)
love.graphics.setColor(0, 1, 0, 0.4)
love.graphics.circle('fill', baseX + radius / 2, baseY - offsetY, radius)
love.graphics.setColor(0, 0, 1, 0.4)
love.graphics.circle('fill', baseX + radius, baseY, radius)
end
