Here in the desert I go with a reddish-brown tile that matches our dirt, and a darker grout.

To a springtime traveler on the Vincennes Trail, the glacial bluff that rose out of the prairie south of Chicago took on a bluish hue from haze of blue wildflowers. 

I think you might want to check out Hue (I think that is the name).

Check out this wireless lighting control called Hue, by Phillips.You can basically create a lighting system just by installing new bulbs and setting up scenes on a free app.They sell them at the apple store. $200 for the starter kit which includes 3 bulbs and the wireless bridge, and $60 each additional bulb. 50 bulbs per wireless bridge.You can do some cool stuff relatively inexpensive.Not trying to spam you, I have no affiliation I just think there cool.

If the water is on now and its left for a few days without being used and you have reddish water out of the taps when you first turn them on, the pipes are rusted on the inside.  

I'm looking at a color by Sherwin Williams called Backdrop (SW 7025) with Extra White trim (7006) with accents if Black Fox (SW 7020) and a hue of a blue grey for the door.

It would be nightmare to see for example the living room has two hues of colors split from the middle, or patched floor when I try to mix boxes.  

All colors have different hues to them, and depending on the type of light, we see them differently.

We then used a dark reddish wood stain sealer on the whole thing and it turned out great!!

Some types of paint-related acids can have a "dyeing" effect on certain (generally darker) hues of brick.
