Could not find this issue previously reported. This issue relates to the colour used to tint all particles during the sunset - sunrise cycle. Smoke and dust look unrealistically colorful due to over tinting of the ambient light.

Example at sunset whilst smoke emitted from a gun barrel would normally be predominantly white around midday it should gradually become less bright as light fades and be SLIGHTLY tinted by the ambient light color.

In ARMA3 these particles seem to be very heavily tinted by the ambient light - this means that white smoke from a gun is bright orange or pink at sunset - likewise dust is far too orange or red during the above low light periods.

It is a matter of subtlety - dust and smoke should be less colorful and slightly whiter. Should be easy to tweak.
