Color wheel, base 12.
# Requirements
- Base 12
# Source
- [ciphertext.jpg](./ciphertext.jpg)- [color-wheel.jpg](./color-wheel.jpg)
# Exploitation
Identify the colors from the ciphertext in the color-wheel, and use numbers 0-11 to write them (like in a clock).
```86 90 81 87 a3 49 99 43 97 97 41 92 49 7b 41 97 7a 44 92 7a 44 96 98 a5```
These are basically the values in base 12. Convert them to base 10, and then treat the values obtained as ASCII.
```python>>> x = "86 90 81 87 a3 49 99 43 97 97 41 92 49 7b 41 97 7a 44 92 7a 44 96 98 a5">>> ''.join(list(map(lambda i: chr(int(i,12)), x.split())))'flag{9u3ss1n9_1s^4n^4rt}'```
Maybe we read some colors wrong? Replace the `^`s with `_`s. 
The flag is:
```flag{9u3ss1n9_1s_4n_4rt}```
