Can any active/former USAF MAC folks help me solve a question regarding the names or FS color callouts for the interior cargo spaces on MAC aircraft (C-130 / C-141 / C-5) utilized primarily in the 1980's and 1990's?

From images on the internet the interior lower half appears a light to medium shade of blue and the upper half is a light to medium shade of tan.

Google queries and visits to various forums on scale modeling cover the exterior colors extensively but little to no information on the interior colors.

I have found that zinc chromate based color was used abundantly thru the late 1950's but then stopped due to it being found to be highly carcinogenic.

I ask this as part of an actual scale modeling project - my wife got me the 1/72 scale Anigrand C-5 as a gift to tinker with...

As always, appreciate any help and discussion offered.
