Notes

Here's implementation for 11.2 and earlier.

function love.math.colorToBytes(r, g, b, a)
	if type(r) == "table" then
		r, g, b, a = r[1], r[2], r[3], r[4]
	end
	r = floor(clamp01(r) * 255 + 0.5)
	g = floor(clamp01(g) * 255 + 0.5)
	b = floor(clamp01(b) * 255 + 0.5)
	a = a ~= nil and floor(clamp01(a) * 255 + 0.5) or nil
	return r, g, b, a
end

Where clamp01 is defined as follows

local function clamp01(x)
	return math.min(math.max(x, 0), 1)
end
