A rainbow flag is a multi-colored flag consisting of the colors of the rainbow. The actual colors shown differ, but many of the designs are based on the traditional scheme of red, orange, yellow, green, blue, indigo and violet, or some more modern division of the rainbow spectrum (often excluding indigo, and sometimes including cyan instead).
The use of rainbow flags has a long tradition; they are displayed in many cultures around the world as a sign of diversity and inclusiveness, of hope and of yearning.
The LGBT community has adopted certain symbols for self-identification which demonstrate unity, pride, shared values, and allegiance to one another. LGBTQ symbols communicate ideas, concepts, and identity both within their communities and to mainstream culture. The two most-recognized international LGBTQ symbols are the pink triangle and the rainbow flag. The pink triangle, employed by the Nazis in World War II as a badge of shame, was re-appropriated but retained negative connotations. The rainbow flag was created to be a more organic and natural replacement without any negativity attached to it.
Varieties of the color blue may differ in hue, chroma (also called saturation, intensity, or colorfulness), or lightness (or value, tone, or brightness), or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a blue or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below.
A social issue (also called a social problem, societal ill, social ill, or social situation) is an issue that relates to society's perception of a person's life, moral character, occupation, etc.. Different cultures have different perceptions and what may be "normal" behavior in one society may be a significant social issue in another society. Social issues are distinguished from economic issues. Some issues have both social and economic aspects, such as immigration. There are also issues that don't fall into either category, such as wars.
Thomas Paine, in Rights of Man and Common Sense, addresses man's duty to "allow the same rights to others as we allow ourselves". The failure to do so causes the birth of a social issue.
