Sometimes I get questions about matching stucco color coating with a similar paint color.

Here is California, one of the major producers of color coated stucco is a company called La Habra. That information can come in very handy when trying to exactly match a paint to an existing stucco color.

A few examples of why you would want to do this are:
1. You need to re-paint just one wall, and don't want the paint to conflict with the existing stucco color coat
2. You want to paint over all the stucco with the same color, to seal the walls against moisture penetration
3. You want to paint over all the stucco with the same color, to eliminate permanent staining of the color coat
4. You're anal, and you just don't like to look at water saturated color coated stucco (there i am :)

Here's a few thoughts to consider if you are ever in this position of deciding how to handle this situation:

1. Get the color code directly from the builder (very do-able if the are still building homes in the development, then it becomes nearly impossible).

2. Assume the stucco is manufactured by La Habra (very possible, they are very commonly used out here in California), and see if you can match the color to their color charts

If you know the year the house was built, you can also probably get color chips for that specific year, in case the color is no longer being produced.

3. Flake off some of the stucco, take it to a paint store, or home improvement store paint department, and computer color match it.

Using options 1 or 2, you would then have the color code, which could probably be used to exactly match a paint to the stucco color.
 
Using option 3, you would have a paint color that very closely resembles the color of the stucco.

In the end, all three options will provide good results, so in terms of best bang for the buck, i would choose option 2, then option 3, and forget about option 1 (too difficult, and not enough benefit for the work involved).

If you are in it for the long haul, consider using an elastomeric paint (more expensive, but much better coverage, much better at sealing the stucco, and much better at resisting cracks from re-opening in the future).

Best wishes, let me know if i can be of any assistance.
