Notes

Here's implementation for 11.2 and earlier.

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