Based on a puzzle given to us by Jamal Senjaya I created a bigger one. Hope it is not too easy.
The number in circle means how many of adjacent triangles should be painted blue.
I did not mention (I was not aware) that the puzzle has many (I hope not too many) possible solutions. There is one however that "makes more sense" - if you see it you will know that this is it. All valid solutions will earn an upvote (hopefully not only from me), but only "the one" will be accepted. The desired solution can be distinguished by the fact that the resulting image is a 4-letter word.
