I assumed you meant INSIDE? Here are interior pictues of a cinder block engine house...gray.

Perth & Exeter Railway Company
Esquesing & Chinguacousy Radial Railway In model railroading, there are between six and two hundred ways of performing a given task.
Most modellers can get two of them to work.
If it is a model of a prototype, a little research should give you the proper color. If it is a freelance, you could do as I did.
The engine house, and other railroad structures, are painted the same yellow as the rolling stock, and locos. ( that reduces the number of colors the railroad has to keep in stock, and, it's less expensive to purchase in bulk.)
We always learn far more from our own mistakes, than we will ever learn from another's advice.
The greatest place to live life, is on the sharp leading edge of a learning curve.
Lead me not into temptation.....I can find it myself!

She is very good with the cutter (in conjunction with a metal ruler) to process and available in various thicknesses and dimensions, the surface (s) are usually not pure white but slightly gray, often there is a smooth and a coarse side. Commercially, they are usually offered in large formats from 70 x 100 cm (27.5 × 39.4 ") and thickness of 1 mm (850 g / m²) to 3 mm (1500 g / m²). <<<<<

For a relatively modern structure like that, blue is a great choice. For a slightly older structure, I'd use a caboose red. Once you get back earlier than that, I prefer straw yellow or a red-brown.

My primary goal is a large Oahu Railway layout in On3
My secondary interests are modeling the Denver, South Park, & Pacific in On3 and NKP in HO
