Hi,
I’m the one on Amibay organizing the front panel group buy. I have a NOS 5 1/4” drive cover and used an colour measurement device to determine its color and RAL9002 came very very close. Hence, we (initial buyers of the powder coated front panels) decided to go for this shade.
If it is not creamy enough, it seems to me that your front panel had darkened already a bit.
