Ive searched all the usual sites, but cant find any sensibly priced white outer gear cables, and inner gear cables for shimano shifters.
Where else can i look?

I’ve got Goodridge white cables, worth the extra bit in my opinion. You should be very happy. If you are able to run them as full length they’re really smooth & look the business…

Thanks where did you buy from

10metre roll of SP41 outer from Parker international does me, not cheap initially, but long term it’s great value & worth it. Inners are much of muchness to me, as I alway lube them up, before fitting & the Sp41 cable is prelubed anyways

I’ve got Goodridge white gear cable outers from CRC. Not especially cheap but look great and definately a cut above in quality.

sp41 as suggested and pop to local electrical suppliers ad get a few meters of white heat shrink, – easiest way to colour code cables!!
xtr inner cables are Very good, bit pricey compared to the std £2-3 ones but silky smooth shifting!

as above SP41 every time

everyone saying sp41 – where do tehy do a white version that teh OP wants?
