I did, but with the samples being smaller it’s a lot easier to get a consistent color on a smaller piece than a whole table. I mentioned in another comment that the issue was more with the application than with actual color
Or... Colour match and make it worth your while by charging accordingly. Most people don't have the skills or knowledge to be able to get colours to match even remotely close. if you've got those skills to active this, you should be paid appropriately for it. If your not prepared to charge accordingly to ensure you dont make a loss, you might as well be stacking supermarket shelves.
I did samples for the customer and they approved of the shellac one. Problem was the sample was a lot smaller and much easier to get a consistent color on. Issue was more of application than with color
