ok.

variable names of 1 letter are very bad. Use more meaningful names like 'red'
'green' etc.

'list' is better, but also a name reserved by Python, so change that too.

Indenting is normally 4 spaces in Python

You can see "a + b +c" twice, compute it once, and assign it to a intermediate
variable

Use string formatting for better readability.

In this case, you could also open the file earlier, and write all strings
directly to file instead of first creating a string in memory

Otherways of creating the colour code permutations: In this case, this is most
Pythonic imho. You could write a list comprehension of even a recursive
function, but I think it wouldn't increase readability.
