Single or multi colour rose bushes?

[MoreChocPls]

I am going to be planting some climbing roses in pots against a wall. Would you go with all the same colour or different? Length of wall be be about 15ft maybe..

I might actually plant using a pillar or oblique …. Just in case that makes a different but they will be very close together.

I would go with one colour.

Agree with one colour. If you wanted succession in your planting you could always plant a complementary colour clematis through it.
