Remove coloring from null values on measure

Hi all,

This must be so easy but I just cannot get my head around it.

I am trying to get rid of the coloring ( or grey it) for the measure that don't contain any value. I am using different legend coloring and each measure has a different color setting. so I cannot use custom sequential ( or maybe I can but I don't know how to make it work)

I cannot post more than this as its a metric dash but this is all there is to it.

Any ideas?
