Why are lighthouses lights red?
They aren't. Most all are white. They might have a red light on the top, but the lights they put out to sea are always white, and sometimes rotate to other colors such as red or green. In any of these designs an observer, rather than seeing a continuous weak light, sees a brighter light during short time intervals. These instances of bright light are arranged to create a light characteristic, or pattern specific to the particular lighthouse. For example, for the Scheveningen lighthouse, time intervals between flashes are alternately 2.5 and 7.5 seconds. Some lights have sectors of a particular color (usually formed by colored panes in the lantern) to distinguish safe water areas from dangerous shoals. Modern lighthouses often have unique reflectors or Racon transponders so the radar signature of the light is also unique.

The color wheel is the lifeline for any serious painter. It graphically shows you what colors to mix to get the effect you want. For example, we all know that the colors in the tubes or jars of paint are intense and gaudy if used as is. So we have to "grey" them or tone them down. This is done by adding it's opposite color, which will be directly opposite of it on the color wheel. The color wheel can also serves as a quick reference if you need a scheme of analagous colors, with maybe a bright contrast.

Ultra violet is a shade of purple that is close to the visible spectrum of light, but just beyond the range of human vision. It is often described as a deep, rich purple with blue undertones.
What are the different colors of the sky?
The sky can appear in various colors depending on atmospheric conditions. Common colors include blue during the day due to Rayleigh scattering of sunlight, orange and red during sunrise and sunset due to longer path lengths of sunlight through the atmosphere, and grey or black during nighttime due to the absence of sunlight. Other colors such as pink, purple, and yellow can also be seen under different conditions.
Why are there different colors in hail?
Hail can have different colors due to the presence of debris or other particles such as dirt or pollutants that the hailstone picks up as it forms in the atmosphere. These particles can get trapped inside the hailstone, giving it a different color. Additionally, the structure and thickness of the hailstones can influence how they reflect light, resulting in various colors.
It is inevitable that all mirrors will have some color. I don't believe that we have found a way to produce a surface that is absolutely perfectly reflective, although we may have come close. If any light is absorbed and not reflected, this will cause a color cast, even if it is extremely slight. Glass also has color, even if it is too faint for humans to detect it.

Why is afterimage green when you stare at a magenta picture?
Afterimages occur when the cones in our eyes become fatigued after being exposed to a particular color for an extended period of time. In the case of staring at a magenta picture, the cones that are sensitive to green light become fatigued, causing a green afterimage to appear when you look away. This is known as a complementary afterimage, where the afterimage color is on the opposite side of the color wheel from the original stimulus.
What are the colours in the balmer series?
The Balmer series consists of visible spectral lines emitted by hydrogen atoms when electrons transition from higher to lower energy levels. The colors in the Balmer series include red (656.3 nm), blue-green (486.1 nm), and violet (434.0 nm) wavelengths.
The night sky, deep ocean waters, some types of flowers (like hydrangeas), and certain gemstones (such as sapphires) are examples of things that can be dark blue.
