What do the colors mean?

# Solution

Nothing special with this challenge, we are given a 64x1 sized png, and we just need to read the pixels rgb vaules as ascii characters.

```py
from PIL import Image

im = Image.open('colorblind.png')
pix = im.load()
print(im.size)

for x in range(im.size[0]):
for y in range(im.size[1]):
for z in range(3):
print(chr(pix[x,y][z]), end='')
```
