If you have nice sized, portable piece of the siding, you can take it to the paint store and have them custom mix color matches for you. Although another option is to find another color to work with the Natural Clay. I assume the stain and paint is for trim, deck, etc. It can be nice, depending on the home of course, to have the body and trim done in different colors.

You'll be much happier in the long run, if you dress those stringers up with Ipe. PT and IPE will never match for very long, no matter what finishing process you use.

Long story, but in a nutshell...We’ve been out of our house for a month and a half at this point and have had nothing but one headache after another. We’ve already had our floors sanded and stained three times. The first time was a bad sanding job so we fired the contractor and found another. The new contractor resanded and stained with the color we chose but we weren’t happy as it didn’t match the sample. We had him sand and stain again. That’s when we wound up with the perfect color but ran out of stain. After spending literally two days on the phone with someone at Bona’s corporate office, as well as with the Bona area rep, we had gotten no further. We wound up using other colors to try our best to match what we have on the rest of the floor. Of course, it doesn’t really match. Needless to say, my excitement at finding the perfect color for our floors has been squashed. Although there is no way to hide the color difference in the area on the main floor where the two colors meet, I am now trying to figure out ways to hide the stairs (paint, runner, etc.).

Find a piece of mahogany like the door, and experiment with different stains, until you come up with an acceptable match. You will need to do the same thing for your fence, since cedar will also stain differently than mahogany.
