Red is my favorite color. You see it everywhere! I love laser pointers because they're almost always red.
Red is the colour at the end of the visible spectrum of light, next to orange and opposite violet.

Laser pointer
A laser pointer or laser pen is a small handheld device with a power source (usually a battery) and a laser diode emitting a very narrow coherent low-powered laser beam of visible light, intended to be used to highlight something of interest by illuminating it with a small bright spot of colored light. Power is restricted in most jurisdictions not to exceed 5 mW. The small width of the beam and low power of typical laser pointers make the beam itself invisible in a reasonably clean atmosphere, only showing a point of light when striking an opaque surface. Some higher-powered laser pointers project a visible beam via scattering from dust particles or water droplets along the beam path.
Laser safety
Laser safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to permanent eye injuries, the sale and usage of lasers is typically subject to government regulations. Moderate and high-power lasers are potentially hazardous because they can burn the retina of the eye, or even the skin. To control the risk of injury, various specifications, for example 21 Code of Federal Regulations (CFR) Part 1040 in the US and IEC 60825 internationally, define "classes" of laser depending on their power and wavelength.
Lasers and aviation safety
Under certain conditions, laser light or other bright lights (spotlights, searchlights) directed at aircraft can be a hazard. The most likely scenario is when a bright visible laser light causes distraction or temporary flash blindness to a pilot, during a critical phase of flight such as landing or takeoff. It is far less likely, though still possible, that a visible or invisible beam could cause permanent harm to a pilot's eyes. Although laser weapons are under development by the military, these are so specialized, expensive and controlled that it is improbable for non-military lasers to cause structural damage to an aircraft.
Laser
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light "coherently", spatially and temporally. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography.
Red
Red is the colour at the end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. The red sky at sunset results from Rayleigh scattering, while the red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide.
Laser diode
A laser diode, (LD), injection laser diode (ILD), or diode laser is a semiconductor device similar to a light-emitting diode in which the laser beam is created at the diode's junction. Laser diodes are the most common type of lasers produced, with a wide range of uses that include fiber optic communications, barcode readers, laser pointers, CD/DVD/Blu-ray disc reading/recording, laser printing, laser scanning and light beam illumination. A laser diode is electrically a PIN diode. The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively.
Pink
Pink is a pale red color that is named after a flower of the same name. It was first used as a color name in the late 17th century. According to surveys in Europe and the United States, pink is the color most often associated with charm, politeness, sensitivity, tenderness, sweetness, childhood, femininity and the romantic. It is associated with chastity and innocence when combined with white, but associated with eroticism and seduction when combined with purple or black. The color pink is named after the flowers, pinks, flowering plants in the genus "Dianthus," and derives from the frilled edge of the flowers.

Red pigment made from ochre was one of the first colors used in prehistoric art

That's...true. Don't think they had many laser pointers back then though. I'm excited that we may be going to Mars, the red planet, soon!
Iron oxide also gives the red color to the planet Mars.

List of The King of Braves GaoGaiGar characters
This is an index of characters and mecha in the anime and manga "The King of Braves GaoGaiGar" and "The King of Braves GaoGaiGar FINAL". A brave man with tremendous courage and enthusiasm, and the strength to never give up for the sake of life—even at the possible cost of his own. Former astronaut and test pilot for the Space Development Corporation. In 2003, he had been in orbit testing an experimental space shuttle when an extraterrestrial object (later classified as EI-01) suddenly appeared in his flight path, smashing his shuttle out of the way. This left the shuttle disabled and Guy himself in a near-death state.

ABC Warriors
ABC Warriors is a feature in the UK comic-book series "2000 AD" written by Pat Mills. It first appeared in program (issue) 119 in 1979 and continues to run as of 2018. Art for the opening episodes was by Kevin O'Neill, Mike McMahon, Brett Ewins, and Brendan McCarthy, who among them designed the original seven members of the team. Since then they have been illustrated primarily, though not exclusively, by Bryan Talbot, Simon Bisley, SMS, Kevin Walker, Henry Flint and Clint Langley. The A.B.C. Warriors are a team of war robots designed to withstand 'Atomic', 'Bacterial' and 'Chemical' warfare. They were built to take part in the long-running Volgan War, which Mills had described in several previous "2000 AD" strips, including "Invasion!"
Exploration of Mars
The exploration of Mars is the study of Mars by spacecraft. Probes sent from Earth, beginning in the late 20th century, have yielded a dramatic increase in knowledge about the Martian system, focused primarily on understanding its geology and habitability potential. Engineering interplanetary journeys is complicated and the exploration of Mars has experienced a high failure rate, especially the early attempts. Roughly two-thirds of all spacecraft destined for Mars failed before completing their missions and some failed before their observations could begin. Some missions have met with unexpected success, such as the twin Mars Exploration Rovers, which operated for years beyond their specification.
