#1- visualise for yourself if you can accept the colour in the long run, you wldnt want to get sick after 1 year looking at the same floor colour.
#2 - pick a colour that is matching and will enhance e whole look of the house with the decor, wall colour, furniture and colour scheme
My own preference is very dark laminated flooring, but eventually i opt for a lighter tone than my 1st choice
because i have dogs at home and the fur colour really contrast with the flooring. Makes the dust and dirt very obvious too.. so this one thing u have to consider
with dark floors.
Bring a few samples and go home n review... so u can make a better choice.
Hopes this helps
