    We can send colors with four unsigned chars.
    Chars are integers, meaning no decimal point, so if the color's r, g, b or a has any decimal points we do math.floor to get rid of them
    We have to make sure r, g, b, and a are between 0 and 255, so we do math.Clamp to make it keep values in that range
    To send unsigned chars instead of chars, we subtract 128 from whatever r, g, b, and a are.
