Searchlight Color

BrendaEM · 08-07-22, 03:05 AM

At night, perhaps, there could be different shades of light for the searchlights.

Where they had smaller incandescent lights, the light would be more amber.

Where they had carbon arc search lights, such as on the destroyers, the light would be blueish, such as this one:

BTW, the searchlight in Wolfpack look cool!

That's an astute observation, and a good idea.

(Thank you @Fidd)

For fun, I mocked up what this effect would look light using a still from one Grim Reaper's videos, which I enjoyed.

This is one of those things that just a little saturation goes a long way, because both a bluish and amber cast would be seen at the same time. Too much and it's not good. BTW, the picture link does not like dropbox.

Pedantic, but also noting because of dispersion and particle/droplet sizes: Viewed from the front steam is gray, but smoke is bluish. Seen through it, steam is still gray, but now smoke is redish-amber.

[So, when the people in New York City banned vaping because it looked like smoking, they must have been smoking some good stuff--in sunlight they aren't that hard to tell apart ; ) ]

Hope you don't mind, and thank you Grim Reaper.
Go, Kortana47!

Hi, you created that effect in the image? That's pretty good, can I use that for reference?

Hi, @Onkel Neal, yes, you may use the pic for reference. I would be flattered, BUT...

I updated and linked another the image to be certain there is no halogen contamination in it: https://www.dropbox.com/s/bzuwfao7xl90zb7/Color%20Temp%202.jpg?dl=0
Also, some larger searchlights have xeon in it. I think that that is not one of those.

Of course, the following colors would have their intensity all the way up, but...

The arc color-coordinates: #b2c8d9 or r178, g200, b217
The searchlight color from: https://www.britannica.com/technology/searchlight-lighting

The incandescent color-coordinates: #fcf2ca or r252, g242, b202
Incandescent color from: http://s3-origin-images.politico.com...ulb_ap_328.jpg

I was really impressed seeing Wolfpack's search lights and head-on glare affects, so much so, it got me thinking about this last little detail.

Other than the brightest lights likely be the arc lights, the designer's discretion to fit them to the ship. In the mock-up, I tended to keep the saturation fairly low. The aim was not to mock up colored lighting, but to show light of different color temperature. The GPU and game-engine color gamut/gradent would have to be considered.

I don't know if in wartime, if they ran the traditional red/green navigation lights? Surely, they would go off id they were under attack. I might research that. So, far I found this color Liberty ship launch, which showed running lights, but no evidence of colored navigation lights.

[The mock-up was done in Photoshop, by eye-dropping the colors, and using a color layer.]

The blue arc-lights would look pretty with red-yellow explosions : )

This one has an explosion in it!

For the mock-up, I made the wide close-in deck lights incandescent, and the others arc. The saturation could even be a bit lower.

[A bit off topic, but still interesting: An article about a WW2 anti-submarine aircraft-mounted light. Not good news for a sub.
