What orange will cover this?

Not sure about the other two, but ginger won't cover it and I don't think the color you'd get from them mixing would be nice looking. Adore ginger is a weird greenish burnt yellow.  I think cinnamon is a light brown color with very slight orange tones, if you want bright orange hair this isn't a great choice to use neat. It might mix well with a stronger orange dye to make a more natural looking red/ ginger. Definitely strand test them and see what you like best.

How about cinnamon and cognac would that give a brownish gingerish colour and how would I go about doing the roots and the rest of hair to get an even job

Adore won't stick to virgin roots, so you will have to process them with either a bleach bath or permanent/demi permanent dye. What colour are they? If lighter than the colour that you want you could get away with just pre-softening with plain developer/peroxide.
Getting an even colour over an uneven base is always tricky, but with direct dyes you can keep tweaking until you have it just right.

Thanks for the replies. So which make would cover Virgin roots and cover the rest of my hair well and not bleed too much? I'm in 2 minds now to go for a gingery colour or just go back to a light brown if possible any advice please 😃

No direct dye will cover virgin hair well, most won't at all and any that do will totally fade within a wash or two. Read Wicked Pixie's post again for ways of helping them stick 🙂
