I am doing a colour change, using Igora Royal 6-78 over old highlights. And 9-7 towards the ends.

Can I mix it with Blondme developer 7vol as I don't have 10 vol. Or would you use 20vol?

20 vol will create lift. So if you're looking to deposit cover only and you're not covering a high % of white then 7vol is probably the wiser option :)
 
Three parts 7 vol + One part 20vol.

(7+7+7+20 = 41. 41÷4= 10.25 Vol.

Thank you, my biggest concern was mixing the blondme product with igora royal.
