Uneven grout color is not normal but there can be a number of things that can cause blotchy grout. Also how uneven the color appears can be somewhat subjective. Certain color grouts are not as easy to control. The easiest colors to work with are the medium grays and beiges as opposed to bright colors, whites, blacks, etc. Since most grout is cement based it tends to turn gray with time and cleaning. Grout sealers are now recommended to reduce this effect.

When grout has been stained to the point that it cannot be maintained or returned to its natural color, you can return the grout back to near its original color or any other color through the use of a "grout stain". Some grout manufacturers make grout colors, others will recommend specific brands that they know work with their grout to correct color. However, grout colorants work best with grout that has not been sealed. See similar questions...

Uneven grout color is not uncommon - although in this case, the darkening may be caused by water (more about that later). This is in part because some colors are more prone to uneven color than others due to the dyes used. Also, depending on the tile, it may be impossible to allow the grout to sufficiently cure for best color uniformity and still remove it from the tile. In other words, the grout must be removed before the color has a chance to set. See similar questions...

For periodic deep cleaning of grout, a concentrated tile and grout cleaner should be used. Concentrated tile and grout cleaner is mixed with water, much like any common household cleaner. The floor should then be mopped and rinsed. Tile and grout cleaners are also available in a spray and wipe version. It is important to use a product specifically designed for grout and tile cleaning as other chemicals can bleach or stain grout. See similar questions...

Again, this is a matter of choice and the look you prefer. Honed stone can usually be butt jointed (tight to each other) with very little grout showing if you want to see less grout or a grid pattern; tumbled stone usually has a 1/8" to 1/4" grout joint which will show off the edges more.

Unfortunately, most new tile installers, never take the time to return and seal the grout lines. Grout is a cement based material that is extremely porous. When cleaned improperly, dirt and liquids stay trapped within the pores and stain the grout. This tends to make the grout color look spotty and dark. See similar questions...

Technically, anywhere there is a change in substrate or backing surface such as the joint between walks and floor and wall joint, caulk should be used in place of grout since these surfaces move independently of each other. However, it is important to recognize and make the end user aware of some important points. Even when the caulk exactly matches the grout color when installed, it may not match 6 months later (Caulk will "age" differently from the grout. See similar questions...
