Door switch panel strange "wood" colours

[HPsauce]

It's been commented on before that the switch panels in the doors, when they are "wood effect" (painted metal!) the colour is significantly different to the rest of the trim.
Though that can also vary somewhat across different items and vehicles that are nominally the same colour.

A while back I replaced my horrid soft plastic door switch surrounds with Vavona effect ones. They look good even though the rest of the car is a different more restrained shade of brown.

Today I decided to revisit swapping some of the other interior trim to Vavona, and in the bright sunlight was reminded why. See attached picture; the top is the OEM trim, consistent through the car, the diagonal unfitted piece is Vavona, I bought a whole set of that and have a number of items left over (sold some) and the switch panel is also Vavona.

As you can see the switch panel works well against the beige trim, but is a very different colour to the rest of the Vavona, nothing like as "orange". I wonder why this is?
