In the beginning I doubted the idea that I can finish this puzzle in 10 minutes. After making the grid a beautiful rainbow masterpiece, I realised I finished the puzzle in 09:09 minutes. Amazing creation!

I opted to colour in the grid before placing any numbers and it went really smooth. A great puzzle.
