Color Saturation & Hue

Looking at the image above, note how quickly the colors lose saturation with distance. Note the high percentage of subdued colors such as gray, pale beige, and burnt umber. Awareness of this reality can go a long way towards improving the realism of our layouts.


Two of the driving elements of visual impact are color treatment and composition. Details matter but don’t catch the eye nearly as much. Today, let’s discuss color, hue and saturation specifically.

Saturation refers to the brilliance, or lack thereof (i.e. fade), of color. Awareness of the impact of the subject can go a long ways towards increasing the realism of our layouts. Culturally, the hobby leans towards deep and vivid saturation and an emphasis on primary colors. Look at the box art on most kits and you’ll see my point. This approach points you in the opposite direction of the real world.

First, regardless of how vivid the color of a prototype surface actually is, the further away you view it from, the more the color disappears. Even a bright red will appear grayish from a half a mile away. We run into a math problem with our models that’s not obvious. Let’s say you’re standing in the aisle and looking at a scene on your layout. You’re only three or four feet away so you get no fade from distance and atmosphere. But…and here’s the problem….you’re a “scale” three or four hundred feet away. In scale terms you should be seeing some fade. In addition, with distance objects quickly appear to lose any gloss they may actually have and assume a dead flat sheen.

The second issue is the selection of the palette itself, color hue. In the real world the vast majority of man made surfaces are: white, slate gray, beige, burnt umber, or oxide (brick) red. As you go back in time to earlier eras this is even more the case, most houses were white or brick.

We can go a long way towards increasing the realism of our layouts by greatly limiting the use of primary colors on our structures, using less saturated colors where we can, and making sure all surfaces have a flat sheen.

DTS Oct. 31 Update

Work continues on Filito’s Market on 12th Avenue. Since the last update, the roof awning was finished as were the banks of security bars along the front.

The steel awning was made from Evergreen #4544 Board and Batten siding. There are angled support brackets underneath made from .060″ styrene. For coloring, I very lightly dusted on Rustoleum Iced Gray from their chalked line of paint. The dusting was light enough that some of the white styrene showed through in places. To bring out the ribs, I gave it a wash of very dilute India Ink and alcohol. ( I think it was roughly 1/2 tsp. per pint)

The banks of security bars were from Tichy. Each bar panel was carefully trimmed. I then lined the bank up against a steel rule and glued a piece of .015″ spring wire along the back with CA to hold everything together. I then airbrushed them with one of Tamiya’s darker grays, I can’t remember which one exactly.

New Miami Book Now Available!

Over the years, I’ve received many requests from my readers to put out a book on my Miami layouts. It took a while, but that day has arrived. The book is now live and available on Amazon. While heavily slanted towards being a photo album, I also cover the thoughts behind the layouts and their history. I discuss the problems that arose and the mistakes I made. I’ve gone back and re-mastered/re-edited many of my older photos.
