I have 5 Ryeland sheep who I would like to breed from this year. Problem is two are coloured and registered and the other 3 are white and non registered

Should I mate them with a coloured or white Ryeland tup? I have looked on the breed society website for guidance and just ended up getting more confused

My thought were to breed with a coloured registered tup so at least the lambs from the coloured ewes could be registered as pure coloureds. Would appreciate any help with this, comments suggestions all welcome

Also does anyone have any Ryeland tups suitable for the job. We are based in Shropshire
