You haven't been very specific about your own tastes in color or how much or little "action" you want to see in the tile. That's probably why people haven't chimed in by now as there could be thousands and thousands of choices that would meet these vague criteria. One of your challenges with tile might be that you are looking at samples, when it might be more helpful to look at pictures of completed bathrooms as it's sometimes hard to visualize from just tile samples. Here is a link to about 800,000 bathroom photos here on Houzz: [Bathrooms[(https://www.houzz.com/photos/bath-ideas-phbr0-bp~t_711) When you go to the link, you can start filtering this mass of photos according to the choices on the left side.

Zaz and Beth, I finally have some samples on my floor to look at (from the Tile Shop) and that's helpful, but it's a pain in the b*** to figure out what samples to order and from whom to order them - and expensive too! I could probably order an equal number of interesting samples from Merola/Home Depot, not to mention the additional ideas you've both now given me, but at some point I need to stop. Even though I feel I've 'narrowed' my focus to something with blue and/or patterned-moroccan-style, there are still so many options and resources to look at. I do like all the additional examples you gave me, Beth. Is EliteTile considered a good quality resource? I have felt comfortable having a retail face to consult with (Tile Shop and Home Depot) but if you and Zaz and others with more experience feel it can be ok to order from a place like Wayfair and this brand of tile, then I feel more confident about that. Both Tile Shop and HD have nice options too, but I've been a bit frustrated that I haven't been able to see an actual sample of a large-size cobalt option .... and the nice on sale lantern blue one is beautiful. What a price, too!! Weirdly, as I look more closely at the Wayfair/EliteTile Moroccan tiles, I'm seeing several that are the exact same patterns that Merola/HomeDepot offer. Do either of you know anything about this? I'd kind of like to add pictures of the samples I have from Tile Shop to see what you both think, but it might need to wait until tomorrow since this day is over and I'm beat. (Also, have other things in addition to tile shopping which I'm sure you both can relate to.) I am grateful to have both of you to converse with on this. Feel more comfortable.

I totally understand your concerns about maintaining congruity with the era of the house. My personal feeling is the the mix of old and new is what makes design interesting. I'm not a fan of walking into say an all modern room in a vintage home. It's jarring. But intentionally integrating a modern element into a more traditional space can be the spark that "makes" it. So, for your bathroom, the larger hex can be a "riff" on the classic tile - that updates it while playing homage to the house's era. At the same time, the use of a solid blue on the floor is already a more modern use of the material. So you could go with a smaller blue hex rather than the larger. I would choose your grout very carefully. I personally don't like a ton of contrast between the tile color and the grout. It just looks really busy to my eye. I also am imminently practical and would never put white grout on a floor. Something in the medium gray range would probably work best but I would have your tile installer make you up a couple sample boards once you get to that point. Smaller hex in a solid color: Grout similar to tile color:

Maybe this houzz quote suggests a gray not too cool, or too warm: "select a trim color - if painting walls a cool color (greens, blues, purples or grays), find a white that reads cooler. Put swatches of white paints next to one another and see how they compare; some will appear more warm or beige-like, and others very light gray with hints of green, blue or purple."
