Silly Squares | 25 points | By Andreas Bratu
I found this marvelous painting of these squares over a red background. It is quite a piece of art. I don't know why I found them so funny, but I can't stop laughing at them. My teacher told me I have to find the flag or I fail. However, the squares are so silly that I can't stop myself from laughing for long enough to find the flag. Can you please find them for me?

Analysis
The image is simple, its canvas with 4 blocks. First block has a flag and others seem to have flag too, but are covered by a different color.
Solution
I used online-image-editor to manipulate image colors.
Upload -> Basics -> Color Change -> Equalize

For the kicks MSPaint can also be used to uncover the flag using bucket tool D:
