On my monitor, the maple has a pink cast, which is intensified by the bluish wall paint (left), so I'd go with the more yellow (but even that has a cooler undertone).. Also, looking at the samples, it seems to me that the color of your hardwood floor might actually go better with the maple than the more greyish tile. (Now, it might be totally different in real life.)

The yellow looks like a good fit, the blue color just does not look quite right.

Don't like the blue. My monitor reads the one on right as a pale green. We're getting ready for a bathroom reno. I'm considering Benj. Moore "Quiet Moments" or "Alaskan Husky". If you want a little more color, BM's "Beach Glass" is a nice one too.

Definitely prefer the one on the right.

The problem is you're asking us to choose a color from how we see the color on our monitor and not on how it looks in real life. Each of our monitors can be calibrated just a bit differently. Think of how when you go to buy a TV and look at them all up on a wall, and each TV's color looks slightly different. It's the same with monitors.

Plus you are looking at the 2 colors on your tile and that's affecting the color around it. Color changes depending on the color surrounding it. Plus you have your current floor color affecting the colors.

Why? Because color doesn't operate in a vacuum. It is influenced by the light and by the colors surrounding it. A color that looks correct in my neck of the woods in SW FL would probably look dull and grayer in the upper midwest because the light coming into the house is different. In FL, the light is actually a bit warmer.

Here are six green squares. Notice how each of the green square colors looks slightly different depending on the background? However each green square is the same exact color. I just copy/pasted it into each larger square. Only the color surrounding the green is different.
