Rats!
I was hoping that this topic was addressing another particular concern of mine - interior color not being an aspect which can be changed in the livery editor.
For two days I just participated in the Minimum Wage Simulator to earn enough credits to buy a Ferrari GTO. I crafted a nice, lightly saturated brown metallic paint & wished that I could pair that with a blonde leather interior. 😒
Staying on topic though, I agree. Many interiors, most often those of older cars, still look too dark to see the instrument panel gauges unless bright ambient light is shining directly on them, QLED notwithstanding. While that contrast is appreciated, I believe it is exaggerated to aesthetically diminishing effect.
