I found this very easy to solve

I found this very easy to solve. When solving puzzles with white in them, just change the background color to one you can see easier. Then the white shows up with no problem whatsoever. Right underneath the puzzle, you have the options to change the grid and main background colors. click on the "color wheel", choose the color(s) and click "apply". Done...and easier to solve. Sometimes you just need to use white as a "color".
