Color wheel, base 12.
- Base 12
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.
>>> 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}
