I've got indian multicolor:
It's not this bright, the lighter tiles blend in a lot more.
The plusses are that it looks great and it does not show dirt and does not stain. If something gets dragged across it it can create a light scratch that simply running a wet sponge over it will make disappear. It feels like an outdoor floor indoors in terms of durability.
The minus is that you can't really use a spongemop to clean it. It wears them out fast because of the roughness (which I should add is totally comfortable underfoot.) I use a Hoover Floormate wet/dry vac, it sucks up all the dirty water and has rotating brushes.
If you're using multicolor, I'd suggest what I did - open all the boxes and lay the tiles out on a driveway and patio and wash them down with the hose really well to remove dust and dirt. Then sort them into piles; mine were "lighter pretty" "lighter boring" "darker pretty" "darker boring" "black/grey" "really really pretty" and "unusable" - those were the ones that were broken, or hand sharp clefts, or had ugly rough inclusions. This was the cheapest HD slate, so you might not have as many rejects.
Then I chose where the "really really pretty" tiles should go, decided to use the black/grey tiles all together in the entryway part of the floor, and told the installers to pick one from each pile, over and over. So it got a good checkerboard pattern.
