Cazza, I'm sure no one intended to lecture you but you have to realise this forum is read by many, many people so it's important we get the "responsible breeding" message across loud and clear. You didn't give much info in your initial post so it wasn't obvious that you realised how much homework you need to do before breeding a litter. As you don't have an experienced breeder to mentor you, you will need all the help and advice you can get but it's hard to give advice if you take offence when it's offered
I asked some genuine questions about what your aims were & why you might want to use a solid stud dog - these questions were asked with the sole intention of helping you with your research but without answers, I can't really give any more advice
Just one other thing, eye testing panellists do not often work in general practice so do check that your vet does offer eye testing under the KC/BVA scheme.
Cayley, I haven't heard of breeders mating particolours to solids to improve colours. Mating recessive to recessive repeatedly can produce wishy washy colouring but to avoid this, you would just breed your orange to a blue roan or black & white, no need to use a solid.
