Sanshoku doujun 「三色同順」 is a standard yaku. This yaku involves sequences of the same numbered tiles across the three main suits. The short hand sanshoku generally refers to this yaku, rather than the significantly more difficult to achieve sanshoku doukou yaku. It can also be referred as sanshiki 「さんしき」.
Tile pattern
Agari :
This hand contains shuntsu of 123 from 3 different main suits. Since this hand played closed, it's sanshoku valued 2 han.
Agari :
Agari : or 
While having same tiles with the first example, these hands played open and hence the sanshoku only valued 1 han.
Value
2 han on closed hand, 1 han on open hand.
Compatability
^ Ippatsu requires riichi to be of any use.

Sanshoku requires three sequence groups, and thus is incompatible with toitoi, sanshoku dokou, sanankou, sankantsu, shousangen, honroutou, and chiitoitsu. It is incompatible with honroutou because honroutou requires either toitoi or chiitoi. Since it requires three suits, it is also incompatible with honitsu and chinitsu. Finally, while ryanpeikou and ittsu do each require sequences, their constraints on the sequences are incompatible with those for sanshoku.
Takame and yasume
Sanshoku is particularly affected by takame and yasume. At times, the tile wait involves a ryanmen looking for two tile types for the third tile grouping needed for this yaku. In this case, one may result in sanshoku, while the other does not; and the difference here may involve 1 or 2 han.
Agari: 
or 
Only the 6-pin produces sanshoku in this case.
Versus ittsu
It is possible for both yaku to have potential development in one hand. However, there is no room in the hand for both yaku to exist. So, when both yaku are apparent, then a point may come during the hand to make a choice between each of the two yaku.
