That is a good question but not be so easy to answer. There are many genes that combine to make colour in the Havanese. Some of these cause colours to continue to develop and change over time. You may not know whether your Havanese has these modifying genes or not until he grows up and you can see the effects of them. Knowing whether and how the colours of the parents may have changed will provide some clues.
Often, changes that start early lead to the biggest differences. Many colours soften to lighter shades.
