orange
I have been 'die-hard' RED fan but Orange is SOOO lovely that I can't decide which one I love the most anymore!There is something incredibly special abt an orange birkin
- great colour - bright n happy yet matches so many colours
- just personal opinion ...
I have RG, orange n beige (out of the colours you mentioned) and no bag makes my heart sing like my orange birkin!
All the best
I'd pick etoupe or gold.
