Color logic

In the game by swipe you should combine colored blocks to get the white color - a mixture of three primary colors: red , blue and green. White block destroyed with the blocks that stand in the same row and column with him. Be careful : after every move on the field there is a new colored block. Blue, red and green blocks can be combined with the same color and saturation blocks for more saturated color. The number of labels on the block indicates its degree of saturation: the first , second or third. Blocks of different colors of the third degree of saturation can be combined with each other:
★ blue + red = purple
★ blue + green = cyan
★ red + green = yellow

★ purple + green = white
★ cyan + red = white
★ yellow + blue = white
