Whar are actual haircolours in our days?
I would say that following some trends in haircolours it is not a right decision, so you may choose your new haircolour according to your preferences and wishes.
You are able to ignore some trends, but I would say that the most trendy colour in our days is natural. I`m talking about natural hair coloured in brown https://lovehairstyles.com/brown-hair-color-chart/ or some blonde colours and highlights, which enhance your previous look.
