Puzzle 217: Coloured Akari

Rules: The challenge is to light up all white cells, subject to the following rules:
  1. Each lit cell illuminates all white cells in a horizontal and vertical direction until the beam hits a black cell or a wall.
  2. Lights are of one of three primary colours, red, blue and yellow with their beams shining a light of that colour.
  3. Numbers dictate how many cells horizontally or vertically adjacent to the cell have lights.
  4. The colour dictate the colours of the co-responding bulbs, if it is a primary colour then only a bulb of that colour may be adjacent to it. If it is a secondary colour then it must have bulbs of two co-responding colours adjacent to it, red and blue for purple, red and yellow for orange and blue and yellow for green.
  5. Beams of the same colour may not occupy the same square, however, beams of separate colours are free to mix.

  1. I think you may have forgotten the rule of "no two lightbulbs may illuminate each other", though I didn't check to see if that's necessary.
