Object: colour adjacent areas with different colours.

Click a gate (black horizontal or vertical bar) in the left board to let a colour flow out or mix with another colour. Click a gate again to close it.
There are two gates at the border, which act as DRAINS, which mean all colour in connected areas will be lost if a drain is open. Drains are automatically closed after each use.

The idea is to colour all white spaces such that no adjacent square areas have the same colour. However, this is not possible, so we allow that one single pair of adjacent square areas has the same colour.

The colour mixing rules for this game:

• Three prime colours (red, blue, yellow) are given.
  Red and yellow mixed will become orange.
  Red and blue mixed will become purple.
  Blue and yellow mixed will become green.
• Mixed colours dominate; e.g., the mix of orange with red will be orange, blue mixed with green will be green.
• Where all three primary colours are in the mix, it will turn black.
• Any colour mixed with black will be black.

Variant 2: You are not allowed to have a black square area in the final setting.
Variant 3: You are only allowed red, yellow and orange colours in the final setting.
Variant 4: You are only allowed red, yellow and blue colours in the final setting.
Variant 5: The three coloured areas which appear at the start have to reappear in the final setting. No black is allowed in the final setting.
All further variants have the target setup given as a second board to the right.
Some variants have a restricted number of gates.

Some if the variants have a solution associated.
