So, we can look at the ratio of the concentration of this guy to this guy. And when the ratio is ten or above, that means we're going to be of this guy, of this color, so of the active color, because there's much more of this than this in our solution. Now, the opposite is true as well. When this guy will dominate, when there is more of this guy than this guy. Now, ratio is 0.1 or less. That means the base color will dominate.
