# Silly Squares

### Description

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](https://www.online-image-editor.com) to manipulate image colors.

`Upload -> Basics -> Color Change -> Equalize`![silly-squares-1](https://1851336151-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FDpkievH4dLdiyHIEAK5Y%2Fuploads%2Fgit-blob-f3f2c4bdf94a1119c4cde254ce8d7c5882ce9475%2Fsilly-squares-1.png?alt=media)

**PS**

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