One of my friends, Anne, is staying in London. She had told me which street she is in but, to my understanding, there are a huge number of houses in the same street. Fortunately, every house in this street has a colour and no two share the same colour. She told me that:

rdo eyw gn? iov t, 13×r+13×s+13×w+13×g

What colour is her house?

Hint:

Addition of the two codes

Deepthinker101 has gotten part way but I think the colour of the house is

GREY

First part

As Deepthinker101 pointed out the first sequence of letters, when taken in pairs, gives rd, oe, yw, gn, ?, io, vt which represent the first/last letter pairs of the colours of the rainbow and the missing set is be representing the colour BLUE

Second part

If we take rot13 of the given letters RSWG, we get EFJT.
This does not mean much on its own but if we add the alphabetical positions EFJT=(5,6,10,20) to the letter positions of the word BLUE = (2,12,21,5) we get (7,18,31,25), or modulo 26, (7,18,5,25) which encodes the letters GREY

Partial answer:

The first statement hints at blue: the letters are organised to spell the letters of the rainbow in order rEd oRANGe yELLOw gREEn iNDIGo vIOLEt and so the missing colour is blue.

  • $\begingroup$ That also fits with the position of the ? and the original clue that was edited out (3665?66) so safe to say that's correct $\endgroup$ Oct 23, 2020 at 12:54
  • $\begingroup$ Yes it's true I'm afraid to say that the previous clue is way harder $\endgroup$
