These Pratt and Larson tiles are buttery. See Harvest, Garland, and Modern Mosaic field tiles.

Nancy, I bow down to you *Bowing in gratitude right now*. I think you found the color! I have been on millions of sites, but not the one you posted. I have also sent for some samples from others and it's so weird that all the yellows I got look Green. It's nice that your site has the yellows up with other colors so you can get a idea of the real color.
Thank you!

If the yellows you got look green in your space, the issue might be with your lighting. Do you have fluorescent or incandescent lighting? Fluorescent runs a bit bluer, so it could make a pale yellow look green--and if that's the problem, the tile Nancy suggested could suffer the same problem. You might have to choose an "orangier" yellow (more saffron than butter), or a more saturated yellow, to get it to come out the way you want.

Or it could be that I'm totally off base.

Oh, and if it is the lighting, you might experiment with paint chips to narrow down what color you need in order to compensate, and THEN start the slower and more expensive process of ordering tiles.

I know what you are saying cawaps but it's the tiles. I sent for two different colors of a yellow in a recycled glass subway and don't know how they even came up with the yellow related names...although I expected the moniter color to be different I didn't expect a whole new color family , one is light green pea soup and one is dark pea soup. The codes were the same as ordered so there was no mixup.
The good thing is that the huge tile store that closed near me hasn't really closed at all, they just shrunk to a tiny space further down. I called and they have samples of the pale yellow Pratt & Larson tiles.
So, some progress and that makes me happy!

Glad to be of help! I saw some of their tiles in person and thought they were so charming. It was too late for me to use them, but I am glad that I was able to steer you towards them. Hope they work out and don't cost a fortune.

cawaps, we are on the same page! After dragging my two tone kitchen samples around looking for a countertop and having no luck I finally got out my paints. I knew at that point I wanted two different granite's plus I had a butcher block little island. So I figured one granite should have a tone of the butcher block but with a little butter yellow tone of the upper cabs. I then mixed up a color sample and found the right granite tone the next time out of the gate. It made it so much easier using a paint tone sample than carrying around a mix of stuff. Now I can get away with using a darker granite over on the sink eat-in counter area.
