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

Nothing.

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

Draw a red, blue and green circle

love.graphics.setColor(1, 0, 0)
love.graphics.circle(50, 50, 20, 20)

love.graphics.setColor(0, 0, 1)
love.graphics.circle(50, 100, 20, 20)

myColor = {0, 1, 0, 1}
love.graphics.setColor(myColor)
love.graphics.circle(50, 150, 20, 20)

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, 100)
	love.graphics.circle('fill', baseX, baseY, radius, 50)
	love.graphics.setColor(0, 1, 0, 100)
	love.graphics.circle('fill', baseX + radius / 2, baseY - offsetY, radius, 50)
	love.graphics.setColor(0, 0, 1, 100)
	love.graphics.circle('fill', baseX + radius, baseY, radius, 50)
end
