Finishing Oak Planks

[Stringman_uk]

Hi (again) All

Continuing the ongoing summerhouse saga, we are now into the final stages.
The oak plank flooring is fitted, and next week I will be sanding them down ready for finishing.
These are solid oak planks.
The walls will be clad in unfinished pine T&G ( may well be washed or painted at a later date) so we want a bit of a contrast.
My original plan was to use a light oak varnish to darken the floor a bit ( the house has pine floorboards with Wickes med oak varnish) but, on reading here, it seems the majority of the coloured varnishes are either not brilliant quality or will over darken ( designed for pine?)

So we have considered Bona Mega silk matt varnish or a Dulux trade varnish. But they seem to be only in clear.
I have now started to look at stains (more work)
I like the look of Manns stains as they seem specifically for oak and also show you pictures of how they will look.

So Is Manns any good?
Any other recommendations?
Or are there any good coloured varnishes?

Thanks in advance
