Color blindness
Color blindness, also known as color vision deficiency, is the decreased ability to see color or differences in color. Color blindness can make some educational activities difficult. Buying fruit, picking clothing, and reading traffic lights can be more challenging, for example. Problems, however, are generally minor and most people adapt. People with total color blindness, however, may also have decreased visual acuity and be uncomfortable in bright environments. The most common cause of color blindness is an inherited fault in the development of one or more of the three sets of color sensing cones in the eye.
Racism
Racism is the belief in the superiority of one race over another, which often results in discrimination and prejudice towards people based on their race or ethnicity. Today, the use of the term "racism" does not easily fall under a single definition. The ideology underlying racist practices often includes the idea that humans can be subdivided into distinct groups that are different due to their social behavior and their innate capacities as well as the idea that they can be ranked as inferior or superior. The Holocaust which led to the genocide of many millions of people based on an ideology of racial hierarchy is a well-known historical example of institutionalized racism, and so is the Apartheid regime in South Africa, slavery and segregation in the US.
Rockin' Dave Allen
David Allen Stich, a.k.a. Rockin’ Dave Allen, a.k.a. Dave Allen, (September 27, 1941 – April 28, 1985) was an American blues guitarist, singer and songwriter. Allen performed live throughout Texas and the Gulf Coast area from the late 1950s through the early 1980s. He recorded for the Jin, Eric, International Artists, Rock-a-Billy and Big Orange record labels for a total of sixteen 45 sides and two vinyl LPs. Some of this material has also appeared on compact disc anthologies by Ace Records. Approximately eighty minutes of Allen’s recordings remain unreleased. Allen was born in Houston, Texas but his family moved to Franklin, a farming and ranching community in central Texas, just before he started school.
Racial inequality in the United States
Racial inequality in the United States refers to social advantages and disparities that affect different races within the United States. These inequities may be manifested in the distribution of wealth, power, and life opportunities afforded to people based on their race or ethnicity, both historic and modern. These can also be seen as a result of historic oppression, inequality of inheritance, or overall prejudice, especially against minority groups. In social science, racial inequality is typically analyzed as "imbalances in the distribution of power, economic resources, and opportunities." Racial inequalities have manifested in American society in ways ranging from racial disparities in wealth, poverty rates, housing patterns, educational opportunities, unemployment rates, and incarceration rates.
Affirmative action
Affirmative action, also known as reservation in India and Nepal, positive action in the UK, and employment equity (in a narrower context) in Canada and South Africa, is the policy of favoring members of a disadvantaged group who suffer or have suffered from discrimination within a culture. Historically and internationally, support for affirmative action has sought to achieve goals such as bridging inequalities in employment and pay, increasing access to education, promoting diversity, and redressing apparent past wrongs, harms, or hindrances. The nature of affirmative action policies varies from region to region.
White privilege
White privilege (or white skin privilege) is a term for societal privileges that benefit people identified as white in some countries, beyond what is commonly experienced by non-white people under the same social, political, or economic circumstances. Academic perspectives such as critical race theory and whiteness studies use the concept of "white privilege" to analyze how racism and racialized societies affect the lives of white or white-skinned people. According to Peggy McIntosh, whites in Western societies enjoy advantages that non-whites do not experience, as "an invisible package of unearned assets".
Visual impairment
Visual impairment, also known as vision impairment or vision loss, is a decreased ability to see to a degree that causes problems not fixable by usual means, such as glasses. Some also include those who have a decreased ability to see because they do not have access to glasses or contact lenses. Visual impairment is often defined as a best corrected visual acuity of worse than either 20/40 or 20/60. The term blindness is used for complete or nearly complete vision loss. Visual impairment may cause people difficulties with normal daily activities such as driving, reading, socializing, and walking.

Oh no! I am so sorry to hear that...Do you have trouble seeing certain colors or is it just red/green?

I have trouble with all colors - apparently it's  an inherited fault in the development of one or more of the of color sensing cones in the eye.

Color
Color (American English) or colour (Commonwealth English) is the characteristic of human visual perception described through color "categories", with names such as red, blue, yellow, green, orange, or purple. This perception of color derives from the stimulation of cone cells in the human eye by electromagnetic radiation in the spectrum of light. Color categories and physical specifications of color are associated with objects through the wavelength of the light that is reflected from them. This reflection is governed by the object's physical properties such as light absorption, emission spectra, etc.
Color vision
Color vision is the ability of an organism or machine to distinguish objects based on the wavelengths (or frequencies) of the light they reflect, emit, or transmit. Colors can be measured and quantified in various ways; indeed, a person's perception of colors is a subjective process whereby the brain responds to the stimuli that are produced when incoming light reacts with the several types of cone cells in the eye. In essence, different people see the same illuminated object or light source in different ways. Isaac Newton discovered that white light, after being split into its component colours when passed through a dispersive prism, could, by passing them through a different prism, be recombined to make white light.
Trichromacy
Trichromacy or trichromaticism is the possessing of three independent channels for conveying color information, derived from the three different types of cone cells in the eye. Organisms with trichromacy are called trichromats. The normal explanation of trichromacy is that the organism's retina contains three types of color receptors (called cone cells in vertebrates) with different absorption spectra. In actuality the number of such receptor types may be greater than three, since different types may be active at different light intensities. In vertebrates with three types of cone cells, at low light intensities the rod cells may contribute to color vision.
Cone cell
Cone cells, or cones, are one of three types of photoreceptor cells in the retina of mammalian eyes (e.g. the human eye). They are responsible for color vision and function best in relatively bright light, as opposed to rod cells, which work better in dim light. Cone cells are densely packed in the fovea centralis, a 0.3 mm diameter rod-free area with very thin, densely packed cones which quickly reduce in number towards the periphery of the retina. There are about six to seven million cones in a human eye and are most concentrated towards the macula. The commonly cited figure of six million cone cells in the human eye was found by Osterberg in 1935.
Gene therapy for color blindness
Gene therapy for color blindness is an experimental gene therapy aiming to convert congenitally colorblind individuals to trichromats by introducing a photopigment gene that they lack. Though partial color blindness is considered only a mild disability and is controversial whether it is even a disorder, it is a condition that affects many people, particularly males. Complete color blindness, or achromatopsia, is very rare but more severe. While never demonstrated in humans, animal studies have shown that it is possible to confer color vision by injecting a gene of the missing photopigment using gene therapy.
RGB color model
The RGB color model is an additive color model in which red, green and blue light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue. The main purpose of the RGB color model is for the sensing, representation and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography. Before the electronic age, the RGB color model already had a solid theory behind it, based in human perception of colors. RGB is a "device-dependent" color model: different devices detect or reproduce a given RGB value differently, since the color elements (such as phosphors or dyes) and their response to the individual R, G, and B levels vary from manufacturer to manufacturer, or even in the same device over time.
