Meh

According to the designers of the overhaul, the yellow and blue was perceived as 'cheap' and the yellow will now be protected as a highlight colour for 'surprises'. Like that tiny, tiny yellow rectangle just aft of the forward door or the crews' uniform ties.
Which means that the majority of people ( i.e. those not flying with DLH ) will no longer associate any yellow with the airline.
It's a bit like Easyjet reliverying black-and-white but keeping orange scarves.
